ci: delete old packages

- add a step in docker-build-and-test to delete old published containers
- should delete all but 'main', 'latest' and release containers
- we have to use my own fork of actions/delete-package-versions
  at the moment to have access to 'dry-run' and
  'ignore-versions-include-tags' features
- [dry-run](https://github.com/actions/delete-package-versions/pull/119/commits)
- [tags](actions/delete-package-versions#104)
