Remove dependency on cache-apt-pkgs-action-ci repo

The action's own workflows (action-tests.yml) already run the same test
jobs as the -ci repo, against the local checkout before merge, so the
separate CI repo is redundant.

- Remove the pub_{master,dev,staging}_push_event.yml workflows that
  dispatched events to the -ci repo (PUBLISH_PUSH_TOKEN secret can be
  deleted from repository settings).
- Point the README test badges at action-tests.yml.
- Port the release-tag tooling (moves the v1 and latest tags) from the
  -ci repo into scripts/release/ and add an update_release_tags
  workflow. Scripts now operate on the current clone instead of
  assuming a sibling checkout, run non-interactively when CI=true, and
  fix the target-tag validation bug in copy_tag.sh.
