Fixes some things reported by make staticcheck. This needs more testing and potentially tests, thus I marked it as a draft for now.

I've now went through all ignored errors. This is ready for reviewing!

If err != nil, then decryption failed for some reason we should tell the user, instead of just saying that there was a MAC mismatch, with the file having a MAC of nil.

I'm pretty sure this should never happen, but it definitely won't hurt to still pass on the error if it actually does.

The return value is always nil. It's mainly returned so you can write comments = store.addCommentsHead(xx, comments) and continue using comments later on. But we have no "later" here, so removing the assignment is best (and makes the linter happy).

Having a test with anchors and aliases surely doesn't hurt.

fix(deps): update module github.com/getsops/sops/v3 to v3.8.1 (#878)
218ddf3 
[![Mend Renovate](https://app.renovatebot.com/images/banner.svg)](https://renovatebot.com)

This PR contains the following updates:

| Package | Type | Update | Change |
|---|---|---|---|
| [github.com/getsops/sops/v3](https://github.com/getsops/sops) | require | patch | `v3.8.0` -> `v3.8.1` |

---

### Release Notes

<details>
<summary>getsops/sops (github.com/getsops/sops/v3)</summary>

### [`v3.8.1`](https://github.com/getsops/sops/releases/tag/v3.8.1)

[Compare Source](https://github.com/getsops/sops/compare/v3.8.0...v3.8.1)

#### Note from the Maintainers

In this release of SOPS, we have focused on landing a variety of bug fixes to improve the overall user experience.

For a comprehensive list of changes, please refer to [`CHANGELOG.rst`](https://github.com/getsops/sops/blob/v3.8.1/CHANGELOG.rst).

##### Important Information for SOPS SDK Users

With the project transitioning from the Mozilla Foundation to the CNCF, the Go module path has been updated to reflect this change in ownership. If you use `go.mozilla.org/sops/v3` as a library, going forward, import the Go Module using `github.com/getsops/sops/v3`. Apart from this small adjustment, the SDK's API remains fully backward compatible.

For a one-liner to quickly implement this change throughout your codebase, please refer to: [https://github.com/getsops/sops/issues/1246#issuecomment-1625526429](https://github.com/getsops/sops/issues/1246#issuecomment-1625526429)

#### Installation

To install `sops`, download one of the pre-built binaries provided for your platform from the artifacts attached to this release.

For instance, if you are using Linux on an AMD64 architecture:

```shell

### Download the binary
curl -LO https://github.com/getsops/sops/releases/download/v3.8.1/sops-v3.8.1.linux.amd64

### Move the binary in to your PATH
mv sops-v3.8.1.linux.amd64 /usr/local/bin/sops

### Make the binary executable
chmod +x /usr/local/bin/sops
```

##### Verify checksums file signature

The checksums file provided within the artifacts attached to this release is signed using [Cosign](https://docs.sigstore.dev/cosign/overview/) with GitHub OIDC. To validate the signature of this file, run the following commands:

```shell

### Download the checksums file, certificate and signature
curl -LO https://github.com/getsops/sops/releases/download/v3.8.1/sops-v3.8.1.checksums.txt
curl -LO https://github.com/getsops/sops/releases/download/v3.8.1/sops-v3.8.1.checksums.pem
curl -LO https://github.com/getsops/sops/releases/download/v3.8.1/sops-v3.8.1.checksums.sig

### Verify the checksums file
cosign verify-blob sops-v3.8.1.checksums.txt \
  --certificate sops-v3.8.1.checksums.pem \
  --signature sops-v3.8.1.checksums.sig \
  --certificate-identity-regexp=https://github.com/getsops \
  --certificate-oidc-issuer=https://token.actions.githubusercontent.com
```

##### Verify binary integrity

To verify the integrity of the downloaded binary, you can utilize the checksums file after having validated its signature:

```shell

### Verify the binary using the checksums file
sha256sum -c sops-v3.8.1.checksums.txt --ignore-missing
```

##### Verify artifact provenance

The [SLSA provenance](https://slsa.dev/provenance/v0.2) of the binaries, packages, and SBOMs can be found within the artifacts associated with this release. It is presented through an [in-toto](https://in-toto.io/) link metadata file named `sops-v3.8.1.intoto.jsonl`. To verify the provenance of an artifact, you can utilize the [`slsa-verifier`](https://github.com/slsa-framework/slsa-verifier#artifacts) tool:

```shell

### Download the metadata file
curl -LO  https://github.com/getsops/sops/releases/download/v3.8.1/sops-v3.8.1.intoto.jsonl

### Verify the provenance of the artifact
slsa-verifier verify-artifact <artifact> \
  --provenance-path sops-v3.8.1.intoto.jsonl \
  --source-uri github.com/getsops/sops \
  --source-tag v3.8.1
```

#### Container Images

The `sops` binaries are also available as container images, based on Debian (slim) and Alpine Linux. The Debian-based container images include any dependencies which may be required to make use of certain key services, such as GnuPG, AWS KMS, Azure Key Vault, and Google Cloud KMS. The Alpine-based container images are smaller in size, but do not include these dependencies.

These container images are available for the following architectures: `linux/amd64` and `linux/arm64`.

##### GitHub Container Registry

-   `ghcr.io/getsops/sops:v3.8.1`
-   `ghcr.io/getsops/sops:v3.8.1-alpine`

##### Quay.io

-   `quay.io/getsops/sops:v3.8.1`
-   `quay.io/getsops/sops:v3.8.1-alpine`

##### Verify container image signature

The container images are signed using [Cosign](https://docs.sigstore.dev/cosign/overview/) with GitHub OIDC. To validate the signature of an image, run the following command:

```shell
cosign verify ghcr.io/getsops/sops:v3.8.1 \
  --certificate-identity-regexp=https://github.com/getsops \
  --certificate-oidc-issuer=https://token.actions.githubusercontent.com \
  -o text
```

##### Verify container image provenance

The container images include [SLSA provenance](https://slsa.dev/provenance/v0.2) attestations. For more information around the verification of this, please refer to the [`slsa-verifier` documentation](https://github.com/slsa-framework/slsa-verifier#containers).

#### Software Bill of Materials

The Software Bill of Materials (SBOM) for each binary is accessible within the artifacts enclosed with this release. It is presented as an [SPDX](https://spdx.dev/) JSON file, formatted as `<binary>.spdx.sbom.json`.
