fix: iOS crash when scenes are enabled

[kononenkoAnton]

Fixes #...

Description

iOS crashes when presenting a view controller while the application is using scenes: https://developer.apple.com/documentation/uikit/app_and_environment/scenes/
The issue occurs because each scene has its own window.

UIViewController *presentingViewController = appDelegate.window.rootViewController.view.window ? appDelegate.window.rootViewController : appDelegate.window.rootViewController.presentedViewController;

presentingViewController returns nil

Steps to verify

1. Prepare an application where scenes are enabled: https://developer.apple.com/documentation/uikit/app_and_environment/scenes/specifying_the_scenes_your_app_supports#3262273
2. On the RN side, call authorize from "react-native-app-auth"

Hey @kononenkoAnton thanks for the PR!

This does seem like it works, but do you think you could provide us with a really stripped down minimal example repo of a RN app that supports scenes as you mentioned.

I haven't used this before and have something clunky set up locally, but would love a reproducible app we could look at/test against in the future.

Let me know, thanks!

Hey @kononenkoAnton - just wanted to give you a friendly ping to see if you'd be up for providing a repro here!

Hey @kononenkoAnton I've been running the https://github.com/microsoft/react-native-test-app without your fix, and it seems like it works correctly still. The RNTA (react-native-test-app) has multiple window support enabled by default and seemed like a good place to test this.

I'm wondering if this might be an issue with your set up instead of an issue with the library.

Let me know if you think you can provide a stripped down example of your implementation, thanks!
