fix: KeyboardAwareScrollView regression after optimization (#1387)

## 📜 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
