Explore using Github Packages instead of Docker for container hosting

[schmidtw]

Since the reuse-action is focused on Github Actions and Github provides free container hosting would the project consider using the Github hosting?

We just ran into cases where docker.io is not allowing authentication & while no hosting service is perfect, Github has a vested interest in keeping Github Actions working and subsequently the Package hosting needed for that infrastructure is critical to Github.

That's weird, thanks for the report. So is this a problem between GitHub Actions (Runner) and DockerHub?

Releasing images on an alternative container registry would be a task for the reuse-tool repo. I've left a comment here: fsfe/reuse-tool#865 (comment)

I'd close this issue here as it doesn't seem to be caused by the reuse action per se. If you disagree, please comment.
