_project.py: Remove unused internal function _extract_plugin_paths()

For reference, this method was added in commit c41f1093, but since commit 4912ed5f it has been unused.

changed the description

Thanks!

I've been hoping to get the linter to find unused private methods but was unable to find out if we can do that with pylint.

I'm not sure if this is doable with pylint. Although https://stackoverflow.com/questions/693070/how-can-you-find-unused-functions-in-python-code suggests vulture or coverage might help.

I tried running vulture on the entire source code to check if there were other unused functions. But I'm not sure if that can easily be integrated into the CI pipeline as it's output is probabilistic and only had 60 % confidence for this function so I'm not super impressed with it.

Maybe coverage can do better but I haven't tried that yet.
