fix: ReactRootView checkForKeyboardEvents to check if rootInsets are set (#35869)

Browse Source 
Summary:
react-native-navigation allows to register React components to be included in the navigation top bar as buttons, the way this work is by using the AppRegistry. When the ViewTreeObserver executes the `CustomGlobalLayout` we are checking for the RootWindowInsets in the `checkKeyboardEvents` which in the case for the top bar component it returns null and the **WindowInsetsCompat.toWindowInsetsCompat** function throws if the insets are null causing the app to crash.

Interestingly in the function `checkForKeyboardEventsLegacy` the null value is being checked, so I guess it was overlooked in the newer function.

## Changelog

[ANDROID] [FIXED] - Fix ReactRootView crash when root view window insets are null

Pull Request resolved: https://github.com/facebook/react-native/pull/35869

Test Plan:
The following videos show how the app crashes as soon as we attempt to pop a screen that contains a react component as a button in the navigation top bar and how it correctly pops to the previous screen after applying the fix
