Need to Upgrade from Python 3.7

While working on #378, I found this error: (see run https://github.com/RTXteam/RTX-KG2/actions/runs/9669257959/job/26675319107)

It looks like we need to update to at least Python 3.8. Should we upgrade more than that, @saramsey? (The latest version of Python is 3.12).

I was able to fix this by downloading https://bootstrap.pypa.io/pip/3.7/get-pip.py instead. However, this seems like a temporary fix.

This is also causing issues with Dependabot:

https://github.com/RTXteam/RTX-KG2/security/dependabot/9

(See commits f2fb19b and 80266d9)

I think we really should look into upgrading the build system so that it can be run on a modern version of cpython. Marking high priority.
