rf(py314): Replace deprecated pkgutil.find_loader (#3384)

This PR removes [pkgutil.find_loader()][] and replaces it with
[importlib.util.find_spec()][]. `find_loader` was deprecated in Python
3.12 and will be removed in 3.14. `find_spec` has been present since
Python 3.4.

Both functions return `None` if the module loader cannot be found. For
its use in this project, this is sufficient and no translation of the
return value is needed.

[pkgutil.find_loader()]:

[importlib.util.find_spec()]:
