Fix test image setup (#289)

- Update docker/* GH actions to their latest versions to get rid of
  warning about the `save-state` command
- Only build images if their Dockerfile has changed
- Drop Debian bullseye & bookworm images as their chromium & ghostscript
  versions have been updated to 120 and 10.0 for security reasons and we
  lost the old images
