Describe your suggestion

1. Make Additional Resources section optional in TOP004 (rewrite rule with simpler TOP-specific custom logic, since the current form is an adapted version of the original Markdownlint rule, which is far more flexible and generic).
2. Remove default content for empty AR section in TOP003
3. Amend docs as necessary:
   • TOP004 docs + tests
   • TOP003 docs + tests
   • templates/lesson-*
   • Layout style guide
