ci : allow make-release to target a specific commit (#27234)
* ci : allow make-release to target a specific commit
The make-release workflow now accepts an optional 'commit' input. When
set, that commit is checked out and the release checks verify that it
belongs to the branch selected in the "Run workflow" dialog and is not
older than 3 days from the branch tip. The check is part of
make-release-checks.sh (driven by the RELEASE_BRANCH env), so it follows
the same dry-run semantics as the other checks.
