fix: KeyboardAwareScrollView regression after optimization

[kirillzyusko]

📜 Description

Call syncKeyboardFrame after keyboardHeight has been set.

💡 Motivation and Context

If we set call syncKeyboardFrame and keyboardHeight = 0, then interpolation simply doesn't work we interpolate between [0, 0] to [0, 0], so we get 0. This regression has been introduced after #1381 changes and in this follow-up PR I'm fixing it 🤞

The fix is quite straightforward - we just need to call syncKeyboardFrame after updating keyboardHeight variable.

Closes #1385

📢 Changelog

JS
