MapView.web.tsx

// Explanation: Different Mapbox libraries are required for web and native mobile platforms.
// This is why we have separate components for web and native to handle the specific implementations.
// For the web version, we use the Mapbox Web library called react-map-gl, while for the native mobile version,
// we utilize a different Mapbox library @rnmapbox/maps tailored for mobile development.
