`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

檢查 warnings.deprecated 的實作和測試，先從 stacklevel 的處理方式，以及 skip_file_prefixes 在其他地方的表示方式開始。連結的 PR gh-156937 是目前需要檢查的工作。完成的標準是 warnings.deprecated 支援針對所述 decorator 和 stack-trace 情況的 skip_file_prefixes，並且有測試涵蓋該行為。
