Align black pre-commit hook version with requirements.txt

[guidoiaquinti]

The black pre-commit hook was pinned to 22.3.0, but requirements.txt pins black==23.12.1. So the pre-commit hook and the dev environment could format code differently. Found while working on #581.

This PR only aligns the two versions; it doesn't upgrade black. Moving to the latest stable black (26.10.0) means first deciding what to do about another pre-commit hook:

• Since 24.1.0, black always puts a blank line between a module docstring and the code after it, and this can't be turned off.
• reorder-python-imports deletes that same blank line. That's true of the pinned v1.5.0 and of the latest v3.17.0.
• The two hooks keep undoing each other, so pre-commit run --all-files never passes. Currently this affects flask_jwt_extended/default_callbacks.py and tests/test_typing.py.

Options for a follow-up:

1. Replace reorder-python-imports with isort (--profile black --force-single-line-imports). This keeps the one-import-per-line style and works with black.
2. Move to Ruff (recommended) for import sorting, linting and formatting, replacing reorder-python-imports, flake8 and black. A bigger change, but it means fewer tools to maintain.

I'll take a look at the black alternatives when I have some time here 👍

Thanks! If you have any pointers or personal preferences, I’d also be happy to put together a PR. Personally, since switching to ruff/ty and uv, I haven’t looked back :)
