[Python 3.11 deprecation] Stop using importlib.resources.path

[webknjaz]

I'm observing

E   DeprecationWarning: path is deprecated. Use files() instead. Refer to importlib-resources.readthedocs.io/en/latest/using.html#migrating-from-legacy for migration advice.

This is caused by import requests which in turn calls certs.where(). The deprecation warning is caused by https://github.com/certifi/python-certifi/blob/ff23c47/certifi/core.py#L38 in the certify-land.

Duplicate of #170. In the future, please search closed and open issues before creating new ones that are duplicates.

Ah, I missed the closed one.

FWIW, for those coming here from Google, here's what you can do in the pytest configuration when running it with filterwarnings = error under Python 3.11, per the best practices:

filterwarnings =
  error

  # FIXME: drop once certifi fixes their use of `importlib.resources`
  # Ref: https://github.com/certifi/python-certifi/issues/183
