pythonGH-95815: Document less specific error for os.remove (pythonGH-…

…99571)

os.remove can raise PermissionError instead of IsADirectoryError,
when the object to be removed is a directory (in particular on
macOS).

This reverts a change done in pythonGH-14262.
(cherry picked from commit 1cae31d)
