Install goreleaser into go 1.18 image for build

[KnVerey]

Closes #4523

We still need to stick with goreleaser v0.179.0 because of #4542, but that doesn't inherently stop us from building with a newer Go version. This PR takes the approach of manually installing the correct version into the official Go container (instead of the other way around as in my previous attempt).

Note: I did not use alpine because it doesn't have bash, and our scripts are written for bash. This didn't actually cause problems so far, but I think this choice is more maintainable and future-proof.

I tested this as described in releasing/cloudbuild.sh, which should be representative since only one container is involved in this solution. But it would still be great if you could test it with cloud-build-local (which still isn't available to me). 🙏

👍 Ran it locally, everything succeeded until the key decryption step as expected.
