Pull Request Overview

This PR improves the documentation examples in the react-x/no-unused-props ESLint rule by replacing generic, unclear examples with more realistic and descriptive React component scenarios. The changes make the rule's purpose and behavior clearer through practical examples.

Key changes:

• Replaced abstract Props/Component examples with concrete React components like Button, UserProfile, and ProfilePage
• Added descriptive comments explaining why each example passes or fails the rule
• Enhanced examples to demonstrate real-world use cases including prop spreading and shared interface usage
