Add new filtering() context manager to LogCaptureFixture class

[jenstroeger]

Closes #11610

Please note that I also added a versionadded:: 7.5 to the method’s docstring, though I’m not exactly sure how you guys handle the version number.

Also, regarding typing of the fixture args please note the recent change python/typeshed#11018 and how with Python 3.12 the return type of the filter has changed. I am not sure how you’d like to handle that, please advise.

This is correct, although we are not sure if there will be a 7.5 release or we will go directly with 8.0; regardless when the time comes we will update the docs if needed.

Not sure, how does that affect the filtering method? It receives a logging.Filter object, which seems correct and won't be affected by that?

Ahh OK, now I read python/typeshed#5700 and understand what you mean. Not sure how to proceed, I think leaving it as you wrote is more pragmatic, as _SupportsFilter is private anyway. Hmm or perhaps we can just copy that protocol over? It is only two lines after all.

Going ahead with this for now, we can improve typing later if we need. 👍

Thanks again @jenstroeger!
