pathlib.Path.unlink raises a `NotADirectoryError` if some element of the path is actually a file - this is undocumented

# Documentation

https://docs.python.org/3/library/pathlib.html#pathlib.Path.unlink states that a `FileNotFoundError` will be raised if the path does not exist.
On macos-14 a `NotADirectoryError` is raised if the directory does not exist.

See pypa/cibuildwheel#1850 for an example.
