Subject: [PATCH 1/3] ci: add zizmor workflow audit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Runs zizmor over this repository's workflows and Dependabot config on
every pull request, on pushes to the default branch and weekly, through
owncloud/reusable-workflows' zizmor.yml. Any finding fails the check.

- dependabot-cooldown: every Dependabot entry waits 7 days before
  proposing an update.
- artipacked: the CI checkout does not persist credentials.
- ref-version-mismatch: setup-php's tag is 2.37.2, without the v.

GitHub still replaces a queued push, schedule or dispatch run with a
newer one in the same group; only cancel-in-progress is limited to pull
requests. Say so instead of claiming only pull request runs cancel.
