Use of deprecated `importlib.resources.path`

[scop]

certifi.core uses importlib.resources.path, which is deprecated in importlib_resources 5.3.0 and thus in Python 3.11, triggering a warning where enabled.

Seems the least intrusive fix that keeps backwards compatibility would be to add another where() implementation that uses the importlib.resources files() API. Can understand if this feels a bit much at the moment, but if for nothing else, FFR.

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

Considering the number of times this is repeatedly reported, I think it would be a good idea to pin one of these to make it prominently visible, like #132 and #72 already are.

Also, if an issue like this would be reported against a project in which I'm involved, I'd keep it open -- it is an unresolved issue after all, even though there is no immediate intent to do anything about it; it's not going to go away/solve itself/by some 3rd party action automatically.
