This PR adds a check to the release checklist script that verifies the
reference-manual release notes title matches the release type:
- For RC releases (e.g., v4.27.0-rc1): verifies the title contains the
exact
RC suffix (e.g., "Lean 4.27.0-rc1")
- For final releases (e.g., v4.27.0): verifies the title does NOT
contain
any "-rc" suffix (e.g., "Lean 4.27.0")
The check looks at the PR branch (bump_to_vX.Y.Z) for the release notes
file
at `Manual/Releases/v4_X_Y.lean` and parses the `#doc (Manual) "Lean
..."` line.
