fix: Check keyboard status during snapshot instead of using WindowInsets listener

[marandaneto]

💡 Motivation and Context

https://posthog.com/questions/status-bar-color-not-updating

I recall fixing something similar in the past as well.
Sometimes the new APIs (setOnApplyWindowInsetsListener) are not well documented on when and how to use them, this is just another weird corner case/side effect.

💚 How did you test it?

Testing the sample app with a different theme and status colors
