`warnings.deprecated` has no `skip_file_prefixes`

Feature or enhancement

Proposal:

Seems like when adding warnings.deprecated in https://github.com/python/cpython/pull/104004, it was forgotten to add one of the two stack skipping arguments.

It needs it for the same reasons why it already got stacklevel, e.g. because adding decorators adds stack levels in a hard to predict way (e.g. a 3rd party decorator might start calling the wrapped function one level deeper, suddenly changing where the warning points)

Has this already been discussed elsewhere?

Yes, and it was accepted, but then apparently fogotten, see link below

Examinez l’implémentation et les tests de warnings.deprecated, en commençant par la manière dont stacklevel est géré et par la manière dont skip_file_prefixes est représenté ailleurs. Le PR lié gh-156937 est le travail actuel à examiner. Le travail est considéré comme terminé lorsque warnings.deprecated prend en charge skip_file_prefixes pour les cas indiqués concernant le décorateur et stack-trace, avec des tests couvrant le comportement.
