Use new REPL for the "code" module

Feature or enhancement

Proposal:

When installing Django in a Python 3.13 virtual environment and using Django's shell command, the old REPL is used.

It would be great if the code module supported the new REPL. From @ambv's reply in https://github.com/python/cpython/issues/119433#issuecomment-2130060062 it looks like this will be considered in Python 3.14.

I would also like to know what projects should do in the meantime. For example, I found a way to modify Django's shell command in one's own project to use the new REPL, by using this within a try-except block:

from _pyrepl.simple_interact import run_multiline_interactive_console
run_multiline_interactive_console()

Is this an acceptable workaround before Python 3.14 is released? Or should this function not be relied on, seeing as it's in an undocumented module?

Has this already been discussed elsewhere?

Start by reviewing the Python code module and the referenced _pyrepl.simple_interact workaround, then read the linked CPython discussion and PR gh-148261. Done means determining how the code module should use the new REPL and clarifying whether the workaround is suitable before Python 3.14.
