Move all demo gifs to github

[kdheepak]

Problem

Currently a lot of the demo gifs are on vhs's website. For reliability, we might want to consider moving them to github.

Solution

We don't want to bloat the repo git history. So we can either:

1. Upload gifs to a separate git repo
2. Upload gifs to a gist in a comment or in a README.md file
3. Upload gifs to a release

also consider using git lfs

also consider using git lfs

Good idea, but we might hit quotas pretty quickly with that:

Demo.gif is 2.8MB, the monthly quota on github's lfs is just 1GiB, and the readme was visited 5475 times in the last 2 weeks (e.g. 15.3GB just for that image), VHS also supports mp4 (651KB->3.6GB), and webm (846KB->4.6GB). I'm unsure how those would render on crates.io, but they look ok on Github. E.g.:

demo.mp4

demo.webm

+1 to the idea. I'd like this to be easy to automate both in CI and locally.

Yeah we totally need this...

I took the approach of creating a new branch to store the gifs. https://github.com/ratatui-org/ratatui/tree/images
