Web build fails for Flutter 3.32 due to platformViewRegistry removal

[jon-mly]

When building with this plugin for web starting from Flutter 3.32, this error is thrown :

../../../../.pub-cache/git/flutter-mapbox-gl-4a09cc4401bb77e900f005cc1e2f712193b997af/mapbox_gl_web/lib/src/mapbox_web_gl_platform.dart:48:8: Error: Undefined name 'platformViewRegistry'. ui.platformViewRegistry.registerViewFactory(

This is due to platformViewRegistry not being defined in dart:ui anymore.

I will be creating a PR to fix the issue.
