name: Backend release

# A version bump on main tags the commit, creates the GitHub release, then
# publishes the backend and frontend Docker images and the PyPI package by
# calling those workflows.
# The release is created with GITHUB_TOKEN, and GitHub never starts workflows
# from events that token produces, so the `release: published` triggers on the
# publish workflows would not fire (0.18.0 got no images that way). Releases
# created by hand still publish through those triggers.
