change: all new layout and tree

[supakeen]

This is a super opinionated new layout of our guides structure. The best way to see what it looks like is to build it for yourself.

@ochosi was it possible to have PRs built automatically?

This PR will be expanded upon.

@supakeen The guide is being built automatically, but as we don't have any place to deploy it we could attach it to the GH Actions run as an artifact.
If you think this would help reviewers I'm happy to do it. Only note that there's unfortunately no easy way to post a link to the artifact to the PR, GH Actions artifacts are a little peculiar in that respect (as in: their URLs will only be available in the API after the GH Action run has completed).
