[python] Add python3.12 (#11478)

Allows for `python3.12` to be used when the build is being run in the AL2023 build container (Node v20 project setting). This version is not usable in the AL2 image because `python3.12` is not installed there.

The e2e tests now default to running in AL2023, except for a few fixtures which require an older version of Python.
