docs: added an ability to show video demos

[kirillzyusko]

📜 Description

Added an ability to show video as demo (before it was possible to show only lottie - but it was expensive in terms of creation).

💡 Motivation and Context

Videos are much faster to create and upload/paste. So I decided to give a try and upload a first video for selection demo (I think when people are having visual reference - it's easier to understand how it works).

📢 Changelog

Docs

• added Video component;
• started to use it in useFocusedInputHandler page;
• corrected documentation for useFocusedInputHandler slightly.

🤔 How Has This Been Tested?

Tested manually on localhost:3000.

📸 Screenshots (if appropriate):

📝 Checklist

• [x] CI successfully passed
• [x] I added new mocks and corresponding unit-tests if library API was changed
