feat(config): switched from os module usage to pathlib

[BSD-Yassin]

Pull Request

Description

Based on #9 : I changed any reference to the python os module to pathlib instead.

Note : Seeing as this is a swap from one default module to another default one, there's no need to update any module dependency. It was already available from >Python3.11
