[BUG] pylint 2.15.7 crashes

[bessman]

Describe the bug
Recently (as in, a few hours ago) my CI builds started failing. The failure is caused by pylint crashing, and coincides with the release of pylint 2.15.7. Running pylint on its own works as expected; the problem only appears when it is run by prospector:

To Reproduce
Run prospector w. pylint enabled.

Environment (please complete the following information):

• OS: Ubuntu latest
• Tool: pylint
• Prospector version: 1.7.7
• Python version 3.11.0

My bad, the error also occurs in earlier versions of python; the CI was using cached versions of pylint for python3.10 and earlier for some reason.

The issue seems to be caused by pylint-dev/pylint@7b82cc8, wherein PyLinter._expand_files was changed to return dict[str, ModuleDescriptionDict] instead of list[ModuleDescriptionDict].
