ClientResponseError: 500, message='Internal Server Error', url=URL('http://snekbox.default.svc.cluster.local/eval')

Which, according to grafana, is snekbox dying somewhere in pathlib while calling scandir.

Sentry Issue: BOT-3EN

Related to Cpython#102613. We should probably switch to glob instead of pathlib for now.

Also related to python/cpython#100282, could remove check after fix upstream
