Description

This MR fixes the currently broken benchmark test and adds a CI job to run the benchmark every time.

The fix doesn't require any changes in astroid. The register_plugins didn't filter .-foldernames (eg. .github) and thus modutils.load_module_from_file was called. Astroid uses importlib.import_module which interprets the . as a relative import. I believe it's highly unlikely that some project would define their plugins in a hidden directory which is why I added a simply filter for it.

Thanks ! I think it also makes more sense to fix it this way.
