name: Bump Version Name

# Opens the next patch line once a version ships to production, through a PR that
# merges itself: VERSION_NAME_BASE, its AppStream <release> entry and the Play
# what's-new, all written by scripts/bump-version-name.py.
#
# promote.yml flips the release to production with GITHUB_TOKEN, whose events start no
# workflows, so it dispatches this one explicitly, as it does winget-publish.yml. The
# release trigger covers a release published by hand; workflow_dispatch is the retry path.
