Codespell ignore list for uppercase words does not work

[nikosavola]

Describe the bug
I tried adding an uppercase word to the codespell ignore list in the pre-commit hook config

To Reproduce
Add an ALLCAPS word close to a typo in the ignore list and somewhere in the code. The pre-commit hook will fail.

Expected behavior
Ignore list works

Suggested fix
This appears to be caused by codespell-project/codespell#2375.
In the meanwhile, the current ignored words should be removed of uppercases.
