`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

Revisa la implementación y las pruebas de warnings.deprecated, empezando por cómo se gestiona stacklevel y cómo se representa skip_file_prefixes en otros lugares. El PR vinculado gh-156937 es el trabajo actual que se debe inspeccionar. Se considera terminado cuando warnings.deprecated admita skip_file_prefixes para los casos indicados del decorador y de stack-trace, con pruebas que cubran el comportamiento.
