`PTH123` wrongly suggests `Path.open()` for file descriptors, only sometimes

[sbrudenell]

Summary

fp = open(1)
def f() -> int:
    return 1
fp = open(f())
def g(x: int) -> None:
    open(x)
r = 1
fp = open(r)

t.py:4:6: PTH123 `open()` should be replaced by `Path.open()`

2 | def f() -> int:

Found 1 error.

This doesn't look like a regression of #12871. But I guess the fix (#13616) somehow didn't cover the case where the argument of open() is an int return value?
