"""Fail if a workflow uses an action by a branch or tag instead of a commit SHA.

A branch or tag can be moved by whoever controls the action's repository, and the
package workflows hand their steps the zmrepo SSH key and the package signing key,
so every `uses:` must name a full 40-character commit SHA. Keep the version as a
comment after it (`@<sha> # v7`) so dependabot can update it.

Run from the repository root: python3 utils/check-pinned-actions.py
