fix: add typing module for python 3.13

[christyjacob4]

What does this PR do?

In Python 3.13, list is now treated strictly as a built-in function, not a generic type hint. Python 3.13 introduces stricter type enforcement, causing conflicts when list[str] is used without from typing import List. Hence we get this error

Traceback (most recent call last):

TypeError: 'function' object is not subscriptable

Hence we use the List that offers computability from Python 3.5+ to 3.13
