Separate out storybook package

[claireolmstead]

Am I right in assuming that a consumer of the package would not be interested in the Storybook UI (that's more for exploring the styles in this repo)? And that the consumer is really mostly interested in the base component/color/font definitions? If that's true, it might be best to separate that out into separate packages, so that the published package only contains the core components and not the Storybook UI. Take a look at the SIWF repository; that's also a Vite/Svelte project with separate packages; some of which are published & some that aren't.

If that's the route we think we want to go, I'd be okay with merging this & make that the subject of a subsequent issue/PR.
