Umbrella for Storybook features

[WilliamKelley]

There are many useful features of Storybook and Chromatic that we aren't taking full advantage of but should:

1. Stories for multiple components
2. Package composition
3. Chromatic TurboSnap (migrated from Investigate Chromatic TurboSnap #159)
4. A11y addon (migrated from Add Storybook a11y addon & Perform audit #128) for a11y audting
   • blog post
5. Design addon for figma embeds / links
6. Links addon for related stories links
7. Use in broader testing flow, read more

Other useful storybook things:

1. CSF stories with MDX docs (migrated from Explore Storybook CSF Stories with MDX Docs #205) - replace /enhance the auto-docs page with our own paragraphs?
   • part of Docs addon
   • Custom templates for the docs page could be a good replacement to our ChangelogTemplate, DocumentationTemplate that isolate underlying component changes / doc links
2. Grid addon similar to above for page layouts
