Add Music Play/Mute Toggle for Better User Experience

I would like to add a music control button (play/mute) to the Pong Game UI. This will allow users to mute background music if they find it distracting and unmute it whenever they want.
This small addition will improve focus and give users control over their experience.

Proposed Implementation -
Add a music toggle button (🔈 / 🔇) to the top bar.
On click:
If music is playing → mute it.
If muted → resume music.
Keep the design consistent with the existing UI.

I’d love to implement this feature and ensure the toggle is smooth and user-friendly.
