Code Review

This pull request migrates the iOS examples of multiple packages to use UIScene and FlutterImplicitEngineDelegate, updating their AppDelegate and Info.plist configurations and bumping package versions. Review feedback highlights that the <key>UIApplicationSceneManifest</key> is missing before the <dict> element in the Info.plist files for extension_google_sign_in_as_googleapis_auth, file_selector, and file_selector_ios, which results in malformed plist files. Additionally, the Google Maps API key initialization was accidentally removed from the AppDelegate.swift of the google_maps_flutter example and needs to be restored.

These changes only affect unpublished parts of the examples, and so fall under one of our documented exceptions to versioning; these should not have version bumps.
