better demos at zellij.dev

[adsick]

Hello, your website looks really good, but I find demos a little too blocky and small.
We certainly can do better either by increasing resolution of these demos or by using a dedicated service that allows for lossless terminal "screencasting" sorry, I've forgot the name of it.

I'm talking about content that can be found on this page: https://zellij.dev/screenshots/

look how bottom's demo looks for example: https://github.com/ClementTsang/bottom
