Ideate on a possible file and folder structure for the docs repo.

Epic issue #469

Come up with some ideas for how we might structure our markdown folders and files in the docs repo.

We started the discussion of what the folder and file structure might look like in the UX + a11y sync today. We talked about the possibility of structuring it by component (to gather all findings for that component in one folder). Amy is going to look into SEO best practices and I want to explore the metadata/tagging capabilities in GitHub repos to see how that can be leveraged.
