py3-black fails with no module named typing_extensions on snapshot 2023-11-07T11:37:49Z

Hi.

I've noticed it today. Sorry for the lack of a diff :/

$ black foo.py
Traceback (most recent call last):
File "/usr/local/bin/black", line 5, in <module>
from black import patched_main
File "/usr/local/lib/python3.10/site-packages/black/__init__.py", line
37, in <module>
from black.cache import Cache
File "/usr/local/lib/python3.10/site-packages/black/cache.py", line
19, in <module>
from typing_extensions import Self
ModuleNotFoundError: No module named 'typing_extensions'

# pkg_info -qI py3-black
py3-black-23.9.1
