Enhance quiz section with interactive answers and improved clarity

Solve this Issue #21
This PR improves the quiz section in the README:

• Wrapping each answer in <details> tags to encourage user interaction.
• Correcting grammatical issues and redundant phrasing in the questions.
• Providing clearer and more accurate explanations for each answer.

These changes make the quiz more engaging and educational for users trying to test their understanding of Generative AI with JavaScript.

Hi @softchris 👋

I've updated the quiz section in Lesson (02-first-ai-app 03-prompt-engineering 04-structured-output 05-rag 06-tool-calling) with collapsible answers and clear explanations, maintaining consistency with Lesson. Please take a look when convenient. Let me know if there's anything else you'd like adjusted.

Thanks again for your feedback and support! 🙌
