fix: No module named 'importlib_resources' (#80)

1. importlib_resources is a backport of....
2. importlib.resources, a standard library package

Redwood and earlier installed (1).
Starting with the [py3.11 upgrade] we dropped (1) in favor of (2).
To maintain compatibility with both, we use a try-except.

Fixes the error on Tutor Nightly:
ModuleNotFoundError: No module named 'importlib_resources'

[py3.11 upgrade] openedx/edx-platform#34788
