Fix #396: split container.yml in two, for releases and testing

As of this commit the responsibility between the two workflows is
delegated as follows:

  1. full arch support will only be available via Docker Hub
  2. GHCR will be solely used for regression testing the Dockerfile

The Docker Hub workflow will only run on new releases (tags), whereas
the GHCR workflow runs on every push to the master branch, and every
new release.
