David Barragán Merino 76763ddd6d 🐛 Fix docker tags not promoted for already-built commits
The bundle and docker-image build/dedup checks used different cache
keys: the bundle was cached by ref name (`penpot-<gh_ref>.zip`) while
the docker image marker was cached by commit sha
(`markers/images-sha-<sha>`). A tag built from a commit already
promoted under another ref (e.g. `develop`) would rebuild the bundle
unnecessarily, while `build-docker`'s `promote` job silently inherited
the skip from `build` and never created that ref's branch tags
(`backend:<gh_ref>`, `frontend:<gh_ref>`, ...), even though the
underlying sha-tagged images already existed.

- Key the bundle S3 object by commit sha (`penpot-sha-<sha>.zip`)
  instead of by ref name, matching the docker marker's semantics.
- Drop the S3 metadata round-trip for `bundle_version` in
  build-docker.yml; compute it locally with `git describe`, same as
  build-bundle.yml (requires fetch-depth: 0 on that checkout).
- Split `promote` into two mutually-exclusive jobs, `promote` (needs
  `build` to succeed) and `retag` (needs only `prepare`, runs when
  `prepare.outputs.exists == 'true'`), each moving the `:<gh_ref>`
  branch tags to the current sha. This replaces relying on `build`'s
  skip/success state with two explicit conditions, so the tags always
  get moved regardless of which path built the images.
