Automate demo gif

[brumhard]

Is your feature request related to a problem? Please describe.

The asciinema preview is often outdated and also requires a webplayer to run.

Describe the solution you'd like

It would nice to create the demo automatically and include it in the README as a svg animation to autoplay as soon as a user opens the repo.

Describe alternatives you've considered

Additional context

https://github.com/brumhard/krewfile already contains a script to automatically create the animation.
One thing that is missing is how to feed stdin to the executed command.

I think https://github.com/charmbracelet/vhs is a much better option now and should be used instead of asciinema.

There's even a github action for that https://github.com/charmbracelet/vhs-action.
