ci: drop go generate from ci pipeline

[rhafer]

All the files generated by the ci-go-generate target should already be tracked in git. So there is not need to run it (multiple times) in the ci.

Thanks for opening this pull request! The maintainers of this repository would appreciate it if you would create a changelog item based on your changes.

It might make sense to just add a single make ci-go-generate step and fail if that generates a diff with the git checkout.

Imho buf generate is not needed in the docs-generate step too.

We should commit the protobuf docs

We should commit the protobuf docs

Fine with me. But then we should IMO still have at least one make ci-go-generate call in the CI to make sure that nothing was forgotten to commit.
