Code Review

This pull request integrates the codespell pre-commit hook to automatically detect and prevent spelling errors in the cognite/ directory. Additionally, it fixes various typos across multiple API and utility files, including corrections in docstrings and comments. Since there are no review comments, I have no feedback to provide.
