Prettier hooks

Pre-commit hooks for Prettier automatically format code and maintain consistent style. Enforce standardized formatting across JavaScript, TypeScript, YAML, and other file types.

Using pre-commit with Prettier is a good way to provide automated linting to your YAML files. With pre-commit, you also get the benefit of only linting/fixing the files that changed.

This makes the formatting process more efficient and ensures consistent YAML styling across your project without unnecessarily processing unmodified files.
