Describe the bug

When i run nox with python warnings enabled the deprecation warning appears:
<frozen importlib._bootstrap>:283: DeprecationWarning: the load_module() method is deprecated and slated for removal in Python 3.12; use exec_module() instead

How to reproduce

Enable python warnings.
run nox.

nox --version
2021.10.1

OS: windows 10

Expected behavior

There is no deprecation warnins appear when i run nox.

Hi @kbaikov Thanks for raising this!

If we have to remove load_module(), I offer to make the switch.

[FollowTheProcess]

This might be bigger than just a straight swap. load_module returns the loaded ModuleType where as exec_module returns None. I tried briefly converting to importlib.import_module as this cropped in a few issues in setup tools referencing the same deprecation warning which also returns a ModuleType but this broke a heap of tests. To fix this properly might require a few plumbing changes to the nox internals

[DiddiLeija]

Good point. Anyway, tell me if I can help with something :)

@FollowTheProcess thank you. That was not a trivial fix! And fast!
