docs: generate component document per registry

[debuggingfuture]

With #62 we built registry at `apps/registry/public/r/@geist/ (.json) aligning shadcn schema

• study shadcn
  • shadcn use mdx to build the docs - example

Goal

• we want to auto gen docs as much as possible.
  • the registry item in .json already pick up jsdoc (title, description of the component)
  • a script generating onto content/ under docs, our build process will pick up and show on sidebar
• the doc for component should show
  • sample command line (with geist registry path)
  • dependencies
• we should integrate storybook
  • for the actual working example
  • low hangingfruit is to embed our hosted storybook (only for deployed components) https://storybook.js.org/docs/sharing/embed
  • we can have the flexibility that if we want customized docs for particular component, we add on storybook (.mdx) and embed
• future potential way is embed the storybook "runtime" onto astro
