envbuilder: create video for release

[johnstcn]

Create video demonstrating Coder <-> Envbuilder integration in a template incl. caching + provider

This may be a post-release deliverable as we would want to showcase the 1.0.0 version as opposed to the RC version.

Do we still want to do this? I'm leaning towards no

How does this look @bpmct ? The emojis are monochrome due to the tool I used to convert the asciinema .cast to a gif.

Here's the original asciinema cast: https://asciinema.org/a/Duce619BrWfs0yNVtv4vwKkQS

Whoops, I missed this! The video looks great. We can link to link to it, or embed it on README.

Thanks Ben! I might try to make it a little smaller though as I forgot how big my monitor is 🙃
