Maybe improve tests by using molecule?

It looks like it's design for running a role in a Docker image, which is the tests do right now, except Github Actions don't allow us to actually start containers with the proper entrypoint (systemd).
And there's something about the docker create && docker start and docker run cycle that doesn't allow containers to last on GH infra, despite docker run working fine on other platforms.
Maybe molecule will overcome that?

Also plausibly crib from Jeff Geerling's work - https://github.com/geerlingguy/ansible-role-php/tree/master/molecule/default
