[RNKC-076] - various small updates for example

[kirillzyusko]

📜 Description

Updated example project with some small fixes.

💡 Motivation and Context

I decided to rework KeyboardAnimation example because of several reasons:

• now two circles stick to the bottom of the screen <- it will be easier to detect any insets changes (these circles will be cut);
• progress value is shown at the top of the screen (it will never be overlapped by the keyboard);
• text input field will be always covered by keyboard;

📢 Changelog

JS

• reworked KeyboardAnimation example;
• added useResizeMode where it was needed to assure, that everything works on API < 30 too;

Android

• set adjustPan for FabricExample on Android (to assure that native module actually changes necessary values);

🤔 How Has This Been Tested?

Tested manually on Android (API 32, API 28) and iPhone (iOS 15.5).
