fix: clean up old pre-commit implementation

Remove the old pre-commit script and rely instead on the pre-commit
command to run the linters. Update the documentation to reflect the
change in how the hook should be configured.

 ### Pre-commit Hooks
 
 The project uses pre-commit hooks to automatically check file formatting:
+
 - **File endings**: Ensures all files end with a single newline
 - **Whitespace**: Removes trailing whitespace
 - **Syntax**: Validates YAML/TOML files
 - **Conflicts**: Prevents committing merge conflict markers
+- **Linters**: Runs the `mypy` and `ruff` linters
 
 These run automatically on commit if installed with `hatch run lint:install-hooks`.
