Broken Windows pathlib behavior in cpython 3.13.0

[JSCU-CNI]

It seems certain Windows pathlib behavior was fixed in cpython 3.13.1. When running cpython 3.13.0, you're gonna have a bad time.

uv run -p cpython-3.13.0 --with pytest pytest tests/plugins/os/windows/test_recyclebin.py
...

Not sure if this can be fixed in the TargetPath implementation or if we should consider this a won't fix.

I'm currently working on pathlib compatibility for 3.14 so I'm fist deep in the pathlib code again, I can take a look.
