feat: Build multipel test containers for codejail.

Before we can test on the newer versions of python we need to build the
new images.  This PR updates the Dockerfile to Ubuntu 22.04 instead of
20.04 and uses deadksnakes to be able to install any relevant python
versions we might need.

We also update the publsh workflow to allow publishing multiple images.
