fix: synchronize bottom padding with keyboard frame in `KeyboardAware…

…ScrollView` (#332)

## 📜 Description

Synchronized bottom padding with keyboard frame in
`KeyboardAwareScrollView`.

## 💡 Motivation and Context

Original regression was introduced in
#257
([these](https://github.com/kirillzyusko/react-native-keyboard-controller/pull/257/files#diff-b4493213c8dc470b5ba251af896d133130cc8996cee1118525e4eba1f3aa993bL87-L88)
code lines). I decided not animated bottom padding to potentially fix
the issue described in
#255 (comment)

However such approach is causing unsynchronized animations in certain
conditions and I'm not sure, that it actually fixes the problem
described in comment above.

So in this PR I'm reworking it again and bringing back animated
transitions 👀

Closes
#329

## 📢 Changelog

### JS

- added `currentKeyboardFrameHeight` variable;
- update `currentKeyboardFrameHeight` variable in `onMove` handler;
- use `currentKeyboardFrameHeight` for bottom padding in KASV.

## 🤔 How Has This Been Tested?

Tested manually on iPhone 15 Pro + e2e tests.
