This PR fixes a release workflow bug where the reference-manual
repository would get tagged with a stale release notes title (e.g.,
still showing "-rc1" for a stable release).
The root cause was a sequencing issue: `release_steps.py` didn't update
the release notes title when bumping the reference-manual toolchain, and
`release_checklist.py` only checked the title while the bump PR was
open. Once merged, it went straight to tagging without rechecking.
Two fixes:
- `release_checklist.py`: add a title correctness check before tagging
reference-manual (blocks tagging if the title is wrong)
- `release_steps.py`: automatically update the `#doc` title line in the
release notes file when bumping reference-manual (handles both
RC-to-stable and RC-to-RC transitions)
