cattrs: Python 3.10 raises ModuleNotFoundError in cattrs/_compat.py

• cattrs version: 23.1.0
• Python version: 3.10.4
• Operating System: linux

Description

In python 3.10, the import of cattrs/_compat is throwing a ModuleNotFoundError.

What I Did

An automated pipeline we are using started throwing a ModuleNotFoundError today. This appears to be related to #364, where the import is not catching the correct exceptions for importing typing_extensions.
