[issue40160] documentation example of os.walk should be less destructive

I think you may have misunderstood the suggestion. 

Specifically, the key part was "I would suggest adding succinct comments or a note that very briefly explains how one could see a visual demonstration...". This would mean the actual code in the example would be *unchanged*, but with a new code comment or separate note after the example that explains how one could replace ``os.remove(os.path.join(root, name))`` with ``print(f"os.remove({os.path.join(root, name)})")`` for a purely visual demonstration that doesn't affect any local files.
