Generate CSV for RHDH

User Story

As an operator developer, I want to have the RHDH bundle manifest generated So that I can simplify the maintenance of this CSV and reduce the potential errors caused by an out-of-sync downstream bundle (especially regarding the operator permissions, as caught for example in #360 and #351).

Kustomize could be a great fit for this, but any better solution is also welcome. Similar to the make bundle command which generates the CSV for the upstream operator (which is version-controlled for review), we could imagine a make bundle-rhdh that would generate the CSV for RHDH off of this upstream CSV using Kustomize overlays/patches. It will still need to be version-controlled for review in .rhdh/bundle.

Acceptance Criteria

• It should add a make bundle-rhdh target that would generate the RHDH CSV off of the upstream CSV (from make bundle)
• It should update CI to auto-push the resulting downstream bundle, similar to what we are doing for the upstream bundle - see https://github.com/janus-idp/operator/blob/main/.github/workflows/pr-bundle-diff-checks.yaml#L63-L99

Do you have an idea what prevents us to auto generate the CSV file for downstream instead?

Since we are moving this repo to rhd/rhdh-operator repo, and there's currently no plan to also contribute this to a backstage/operator repo, this will likely be not required.

Instead we can merge the two CSVs into a single downstream one and simplify the resulting repo.

As part of the migration from janus-idp to redhat-developer in https://issues.redhat.com/browse/RHIDP-1021, this will be tracked in https://issues.redhat.com/browse/RHIDP-2387 and https://issues.redhat.com/browse/RHIDP-2389
