Create sample content/examples in rich format

For kool 2.0, we need a new demo video using kool preset instead of kool init

[danielsuguimoto]

After merging #198, we also can use the new create command on the demo

One option I find interesting is recording using https://asciinema.org/ and then publishing to our Blog https://blog.kool.dev.

The repo here can always have only an image linking to the blog post.

Closing this because we already have some asciinema demos. The README has already been updated to point to https://asciinema.org/~kooldev

There is active work happening and soon there will more examples over there.
