This PR enhances iOS notification permission handling to include CarPlay notification permissions on iOS 10.0+ devices. When users request notification permissions through this plugin, CarPlay notifications are now automatically included, providing comprehensive notification support across iPhone and CarPlay environments.
Changes:

• iOS Native Implementation: Updated NotificationPermissionStrategy.m to:

  • Request UNAuthorizationOptionCarPlay when requesting notification permissions
  • Check CarPlay notification settings when determining permission status
  • Gracefully fallback for devices older than iOS 10.0

• Documentation: Enhanced Dart-level documentation in Permission.notification to clearly explain iOS behavior includes CarPlay

• Main Package Updates:

  • Updated README to document CarPlay inclusion in Podfile comments and permission table
  • Added CHANGELOG entries for both permission_handler (12.0.2) and permission_handler_apple (9.4.8)
  • Updated dependency version to reference new Apple package version

Closes: #1514
