Upgrade codejail-service from Python 3.8 to 3.12

[robrap]

1. This requires us to first be on the new containerized codejail-service.
2. We want to use the codejail-service dark-launch capability, but this will need to be enhanced to handle 2 external codejail services from the edxapp. An initial version of this should have already been added to edxapp, but it would have been used to compare a local codejail to the service.
3. SRE will need to be able to stand-up the second codejail service in parallel in order to use the dark-launch functionality.
4. See https://2u-internal.atlassian.net/wiki/spaces/AT/pages/16385128/Code-jail+Upgrade+and+Testing

Once the above is in place, we can have a rollout plan that compares 3.11 to 3.8 results and ensures there are no problems before switching to the newer version. If problems are found, we need to communicate with partners. We probably need to communicate with partners in all cases regarding the plan.
