Update test_allFileMetadata.py

[Khushi-Dua]

Here's a brief analysis of the code:

1. Path Handling: The temp_file fixture unnecessarily converts the Path object to a string. Returning the Path directly makes the code more readable and compatible with file operations.

2. Error Handling in Non-Existent File Test: In test_get_modification_time_non_existing_file, it’s important to ensure that the function properly handles non-existent files, returning -1 or a suitable error.

3. Enhanced Assert Statements: Adding specific messages in assert statements improves test readability and debugging, making it easier to identify issues if a test fails.

These adjustments streamline the code and enhance clarity without altering its core functionality.
