docs: fix a few typos in CHANGELOG.md and .pre-commit-hooks.yaml

[yarikoptic]

I saw that there were typo fixes in CHANGELOG.md in the past (e.g. 90e2fd8) so decided to do again.

Ran codespell -w while on top of

• style: move codespell configuration to pyproject.toml #1136

so to have proper config available.

Note that when I did pre-commit run codespell --all I think it ignored CHANGELOG.md

❯ pre-commit run codespell --all
Run codespell to check for common misspellings in files.......................Failed
- hook id: codespell
- files were modified by this hook

FIXED: .pre-commit-hooks.yaml
