Integrate Pagefind full text search with Storybook

[jrencz]

Is your feature request related to a problem? Please describe.

Storybook, when it grows, may become hard to browse. It's built-in search component is helpful navigating as long as one knows what they look for, and as long as they keyword happens to be te name of component or the title of docs page

Describe the solution you'd like

I'd like to draw maintainers' attention to tool called Pagefind

As I wrote earlier today #7711 (comment) it brings a great experience to one of existing static docs generators, https://starlight.astro.build/ and I suppose it may be useful in Storybook as well

Describe alternatives you've considered

No response

Are you able to assist to bring the feature to reality?

yes, I can

Additional context

Output of Astro is easy to index because it's a static HTML with a bunch of JS inside and therefore it's possible to use Pagefind CLI

For Storybook it will probably be required to use indexing API instead during storybook build as what comes out of build is (at least in case of Vite builder I use and I can observe) a bunch of JS files with raw JSX runtime functions calls so running CLI against that may not give good results

I stumbled upon this feature request in search for a full text search for my MDX files in Storybook.
I've created a simple nodejs script that uses the pagefind node api to inject custom entries. I use a glob pattern to find all mdx files in my story folder and use the index.json to figure out the urls for the files. So this is very doable for plain text files.
