Update test documentation for Windows UNC paths in test_windows_compatibility.py

- Changed the docstring to use a raw string literal for better handling of backslashes in UNC path examples.
- Clarified the description of UNC paths to ensure accurate representation of their format.

These updates improve the clarity and correctness of the test documentation.
