Publish to Github Packages

[jberger]

With Docker Hub implementing rate limits it might be nice to also send images to github packages. One might even consider using github actions to build the images and push them to both places.

Yep, this is on my pipeline 💪 I'm actually considering publishing a GitHub Action here to automate using docker-perl for whatever use, not just CI...

I think let's limit ghcr releases to those that we don't already provide under docker-library - so things like

• debug versions
• releases using alternate base images (e.g. fedora)
• pre-release versions upon request
