Add FAQ Section to README.md for Better User Guidance

[Diksha-3905]

This PR adds a new FAQ (Frequently Asked Questions) section to the README.md file.

Changes include:

• Common questions new users might have.
• Clear, concise answers to help users get started more easily.
• A formatted layout to match the existing README style.

This addition aims to improve the overall user experience by reducing confusion and support questions. Feedback or suggestions for more questions are welcome!

Thank you!

I added a FAQ section to the README.md file to help new users with common questions. This improves usability and reduces the learning curve for beginners.

Let me know if you'd like to add or modify any of the questions in the FAQ.
