Move dev deps to dev deps, remove some unneeded deps

[david-crespo]

I noticed that oxidecomputer/console#2626 adds ton of stuff to the lockfile that doesn't seem necessary — stuff that should be build-time deps only. I think it has to do with things being dependencies that should be in devDependencies.

1.8.2

1.8.3 canary (this PR)

Still more stuff than I would like to see in the lockfile, but it doesn't really matter. Eventually it might make sense to separate the design tokens from the asciidoc stuff so you can get one without the other.
