Two blockers stopped the restored GitHub release workflow from actually
publishing (green run, no publish):
1. package.json repository/bugs/homepage still pointed at Codeberg, so
   semantic-release operated against the diverged Codeberg remote and saw the
   GitHub checkout as 'behind the remote' -> skipped the publish. Repointed to
   github.com/ConductionNL/nextcloud-vue (canonical).
2. release.yml checkout was detached (no ref:), amplifying the same skip. Add
   ref: github.ref_name to track the branch head.
