ISSUE
The test buildscripts/tests/resmokelib/testing/test_suite.py::TestGetTestsForKind::test_simple fails when run with Python 3.13 but passes with Python 3.10.

Error:
TypeError: startswith first arg must be str or a tuple of str, not NoneType
  File "buildscripts/resmokelib/selector.py", line 225, in _evaluate_paths
    if len_after == len_before and path.startswith(
        self._test_file_explorer.get_jstests_dir()  # Returns None
    ):

ROOT CAUSE
Python 3.13 changed the behavior of glob.glob() when matching patterns against non-existent directories.

Python 3.10 Behavior:

• glob.glob('testroot/**', recursive=True) returns ['testroot'] even when testroot doesn't exist
• This is a "phantom result"

Python 3.13 Behavior:

• glob.glob('testroot/**', recursive=True) returns [] when testroot doesn't exist
• This is the correct behavior

The change was made in the _glob2() function in Python's glob module:
