ci: fix release workflow (#5030)

- Don't run the Release job with a matrix because we don't want to run
  release-please and the git tag steps more than once.
- Don't get release metadata if release-please didn't create the release
  yet.
- Populate the container image build cache.
- Set the starting version and commit for release-please.
