bpo-34825: Add more entries to os to pathlib reference table (GH-9608)

The added functions are as below :

| os module     | Pathlib       |
| ------------- | ------------- |
| os.chmod   | Path.chmod  |
| os.mkdir  | Path.mkdir  | 
| os.rename | Path.rename |
| os.replace | Path.replace |
| os.rmdir  | Path.rmdir |
| os.remove, os.unlink | Path.unlink |
| os.path.samefile | Path.samefile |

Thanks
