Update gallery.tsx (#1403)

🔧💡 Fix: Enhance product gallery layout in product view page

- 🖼️ Implemented `flex-wrap` for the sub-gallery images.
- 🛠️ Ensured images wrap automatically when they exceed 5 or 6, preventing overflow and maintaining responsive design.
- ✅ Confirmed that the layout remains unaffected for galleries with 3 or fewer images.

This improvement enhances user experience by making sure large image sets are displayed without affecting screen layout.
