PTH123 suggests Path.open() which does not support file descriptors

[sbrudenell]

fp = open(2)

$ ruff --version
ruff 0.5.7
$ ruff check --isolated --select PTH123 t.py
t.py:1:6: PTH123 `open()` should be replaced by `Path.open()`

Found 1 error.

Path.open() doesn't seem to have a variant which supports a file descriptor.

This is essentially similar to #7620
