style(ci): fix YAML formatting in pre-commit hooks workflow

Remove trailing whitespace from lines 134 and 338.
Fix double blank line spacing between sections.
Ensure compliance with .editorconfig rules.
Maintain proper indentation and line endings.

This resolves the CI formatting violations that were preventing
the workflow from passing YAML lint checks.
