name: Trigger Release

# Release flow:
# - Run *this* workflow from the internal repository.
# - This will create and push a version bump commit and tag it.
# - ci.yml's sync job will trigger and sync both the commit and tag to the external repository.
# - The tag push will trigger the external repository's release job.
