* [pre-commit.ci] pre-commit autoupdate

updates:
- [github.com/psf/black: 22.12.0 → 23.1.0](psf/black@22.12.0...23.1.0)

* [pre-commit.ci] auto fixes from pre-commit.com hooks

for more information, see https://pre-commit.ci

* Advance flake8-docstrings to 1.7.0.

* Ignore flake8 D202, as the rule is permissive and disagrees with Black.
