Compatibility issue with Python < 3.9 due to type hinting

Discord Version

Pycord 2.5.0

Bug Description

Hi.

Trying to run Pycord bot with the 2.7.0 version of chat_exporter results in the below error:

  File "C:\Users\laiye\.conda\envs\dvbot\lib\site-packages\chat_exporter\ext\cache.py", line 27, in decorator
    def _make_key(args: tuple[Any, ...], kwargs: dict[str, Any]) -> str:
TypeError: 'type' object is not subscriptable

This error seems to stem from the type hinting used in chat_exporter/ext/cache.py, specifically with tuple and dict.

In Python versions older than 3.9, subscript notation for built-in types without importing from the typing module (like Dict, Tuple) isn't supported. I was using Python 3.8.15.

PR #101 imports Dict and Tuple from typing, allowing this library to support versions older than 3.9.
