`test_strptime` locale failures on `Windows` for rare languages

Bug report

Bug description:

On Windows, test_strptime fails for rare locales (e.g. aa_ET, om_ET, so_SO) because locale data is missing for these languages. The same tests pass on Linux, where the relevant locale data is available.

Example error:

AssertionError: Tuples differ: (8, 9, 28) != (20, 9, 28)
: testing of '%X' format failed; '8:09:28...' -> (8, 9, 28) != (20, 9, 28)

Expected behavior

Skip tests for locales that are not available or not supported on the current platform.
If this is acceptable, I am willing to submit a PR.

CPython versions tested on:

CPython main branch

Operating systems tested on:

Windows

Can you please post the full verbose output? When I (on UNIX) change my LOCPATH to an empty directory the tests are skipped already, e.g.:

test_TimeRE_recreation_locale (test.test_strptime.CacheTests.test_TimeRE_recreation_locale) ... skipped "no locales ('en_US.UTF8',)"

Sorry, I checked my command-line code, and found that I actually used Python 3.13 for testing. When I use ./python.bat, they were indeed skipped.
