Store default Mapbox iOS and Android versions in package.json (#4081)

This change centralizes the default Mapbox SDK versions in package.json
instead of hardcoding them in platform-specific build files.

Changes:
- Added "mapbox" section to package.json with iOS and Android version fields
- Updated android/build.gradle to read default version from package.json
- Updated rnmapbox-maps.podspec to read default version from package.json
- Updated scripts/autogenHelpers/generateCodeWithEjs.mjs to read versions from package.json

This makes version management easier and provides a single source of truth
for default SDK versions. Users can still override these versions using
$RNMapboxMapsVersion (iOS) and RNMapboxMapsVersion (Android) as before.
