feat(storybook): add project

[MFarabi619]

What problem will this feature address?

Docs projects have become a staple in modern monorepos, and continue to have a growing focus on outstanding UI aesthetics.

A current pain point with the UI components documentation experience in Fumadocs is the ability to quickly experiment with and view various states of the components.

Describe the solution you'd like

I've already shipped storybooks containing Fumadocs UI components to production, here's an example.

The ability to quickly change the state of a component and see the code has been an enormous boost to developer experience. It makes the components self-documenting, and eases onboarding greatly to open-source project by lowering the 'finding UI components' curve in the codebase.

I was an early adopter of Fumadocs, and realized its potential very quickly. Here's one of my early projects where I made the attempt to bring this vision together.

Describe alternatives you've considered

The following alternatives exist...

Histoire	StoryLite	Astrobook	React Cosmos

and can be added as examples in the future as well. The goal would ideally be to leverage the Component Story Format - CSF as much as possible to avoid the maintenance burden.

I'd be interested in working on this later down the line and have existing examples I can draw from.

I think it's better to let devs trying out the components locally in their editor instead of with docs, an embedded editor like CodeSandbox makes more sense if that is needed.

[MFarabi619]

That's fair, let me play around with CodeSandbox a bit and prepare some proof-of-concepts.
