Start installing codejail requirements from base.txt instead of py38.txt

[timmc-edx]

The structure of the edxapp-sandbox-requirements has changed and we need to switch in order to keep getting updates: openedx/edx-platform#34509

First step: Determine priority, may be able to lower it.

Nice, you caught this before I got around to bugging you about it :) Just a heads up, as I tried to explain here, we plan to keep requirements/edx/base.txt and requirements/edx-sandbox/base.txt synced in terms of constraints and language version. So, once Py3.8 support is dropped from edx-platform, it will be simultaneously be dropped for edx-sandbox. That might be exactly what you folks want, or it might not be, I'm not sure--just want to make sure you folks have all the information you need as you decide between quince.txt redwood.txt and base.txt.

Putting down a due date of "something like the Sumac release", so that we dont lose this. The thought is that this can be added to a "pipeline" related epic in H2 2024.

Noting that it is entirely up to 2U when we want to get off an unsupported version of Python. It would be good for us to clean-up the unused file once we are done with it, but Axim does not plan on deleting this file. In other words, we don't have an external deadline for this work.

Additional questions:

1. Would it makes sense to move to Python 3.12 (rather than 3.11) to minimize the number of upgrades?
2. Would it make sense to bump Ubuntu versions to minimize upgrades? See Test edx-platform on Ubuntu 22.04 openedx/edx-platform#35314

Note: Ubuntu 20.04 standard support runs out April 2025, and this upgrade work may need to be ticketed separately with SRE. I simply wanted to note that we need to take some action somewhere.
