Python 3.13: test_assert_valid_name_minimal fails due to changed behavior of PurePath.is_reserved()

[penguinpee]

According to upstream's documentation the behavior of PurePath.is_reserved() has changed in Python 3.13:

Changed in version 3.13: Windows path names that contain a colon, or end with a dot or a space, are considered reserved. UNC paths may be reserved.

Besides the change in behavior, the is_reserved() method is deprecated as of Python 3.13 and will be removed in Python 3.15:

Deprecated since version 3.13, will be removed in version 3.15: This method is deprecated; use os.path.isreserved() to detect reserved paths on Windows.

The change in behavior leads to test_assert_valid_name_minimal failing when asserting validity of path "\n":
