When running the Pip detection for setup.py files, there were extra unicode characters being added to the normalized path strings. This will fix that issue by normalizing to / which is valid on both Unix and Windows.

👋 Hi! It looks like you modified some files in the Detectors folder. You may need to bump the detector versions if any of the following scenarios apply:

• The detector detects more or fewer components than before
• The detector generates different parent/child graph relationships than before
• The detector generates different devDependencies values than before

If none of the above scenarios apply, feel free to ignore this comment 🙂
