--select=PTH120 does not work

[skraeven]

Selecting PTH120 rule seems to always return 0 errors.
The workaround is to drop the 0 (--select=PTH12) to actually get the errors.
I'm not aware of any other rules that has this behavior.

Example:

$ ruff check . --select=PTH120 --isolated
All checks passed!
$ ruff check . --select=PTH12 --isolated
test_pth120.py:3:1: PTH120 `os.path.dirname()` should be replaced by `Path.parent`
  |
1 | import os
2 | 
3 | os.path.dirname("foo/bar/baz")
  | ^^^^^^^^^^^^^^^ PTH120
  |

Found 1 error.
