Improve spell checker using codespell

* Configures automated spell checking with codespell
Adds GitHub workflows and configuration files for automated spell checking using `codespell`.

This includes:
- A workflow for checking pull requests and preventing new typos
- A workflow for automatically fixing typos in the main codebase
- Configuration files for `codespell` to ignore specific terms and file types
- Documentation on how to use and configure the spell checking workflows.

* Corrects minor spelling and grammar errors.
