`KeyboardAvoidingView` animation issues since 0.76+

[alexmngn]

Description

I've updated my project from 0.75.2 to 0.76.1 this morning, and I noticed that the KeyboardAvoidingView, which was previously animating properly, is no longer animating. It now jumps and doesn't follow the keyboard animation.

Not sure why in my project it doesn't work, but while creating the reproduction repo, I noticed the animation behaviour has changed and doesn't look native smooth anymore.

Steps to reproduce

Hey @alexmngn, thanks for opening this issue.

Does it happen with the new architecture too?
