[iOS] privacy manifest

[nirmalraj2000]

Since Apple mandated privacy manifest starting may 1 2024, I am migrating all my plugin to include privacy manifest

chewie: ^1.8.1 depends on video_player: ^2.8.3 which does n't include privacy manifest, where as video_player: ^2.8.6 contains privacy manifest

Please update the version of the chewie, since it is really important for our app
