Action to clean up containers from ghcr.io

This action old deleted docker containers hosted on ghcr.io. The action expects containers to have incremental numeric semver-like tags. Any version that can be coerced to a semver version works (e.g. 1.2 or 2.3.4).

For tagging of containers I use tags formatted as <MAJOR-NUMBER>.${{ github.run_number }}.
