docs: reorganize the About section (coder#18236)

As part of an information architecture overhaul, this PR reorganizes the
About section and adds a Support section (but not content to it yet)

[preview](https://coder.com/docs/@docs-ia-about/about)

this PR is intentionally limited in scope so that we can ship meaningful
changes faster and followup PRs should include:

- [ ] edit + overhaul the About page
- [ ] decide on the `start` directory
- [ ] ~screenshots page updates~ (this should happen July or later)
