Specificying a different python version doesn't change the container python version #840
Description
template_config.yml has a python_version setting which only appears to change the version of python that is running on github actions, but not inside the pulp test container itself. This setting is misleading and should configure the python version in the github worker as well as the test container.
Galaxy NG needs this functionality as we have to test newer python versions in order to maintain compatibility with AAP.
