Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## 📜 Description

Added optional chaining instead of forced unwrapping. Fixes crash
described in
https://github.com/kirillzyusko/react-native-keyboard-controller/issues/93

## 💡 Motivation and Context

In fact it's not a fix and is more avoiding NPE rather than a full fix.
But anyway, missing animation is better, than a crash of application
🤷‍♂️

## 📢 Changelog

## 🤔 How Has This Been Tested?

Tested locally on:
- iPhone 13 Pro (iOS 15.0);
