'keyWindow' was deprecated in iOS 13.0

Issue

'keyWindow' was deprecated in iOS 13.0 : Should not be used for applications that support multiple scenes as it returns a key window across all connected scenes

Where

GADManager.swift:455, 459

Solution

1. Add extension for UIApplication

extension UIApplication {
    var keyRootViewController: UIViewController? {
        guard let windowScene = UIApplication.shared.connectedScenes.first as? UIWindowScene else { return nil }
        
        return windowScene.windows.first(where: { $0.isKeyWindow })?.rootViewController
    }
}

2. Replace keyWindow... with keyRootViewController

iOS 13.0 deprecation fix completed

• Read GADManager.swift to understand current usage
• Add UIApplication extension with keyRootViewController
• Replace keyWindow usage at lines 455, 459
• Commit and push changes
• Provide PR link

Summary

Fixed the iOS 13.0 deprecation warning for keyWindow by:

1. Added UIApplication extension with keyRootViewController property that safely gets the root view controller from the first connected window scene
2. Replaced deprecated calls at GADManager.swift:463 and GADManager.swift:467 (originally lines 455, 459)

The solution follows the recommended approach for supporting applications with multiple scenes in iOS 13+.
