Summary of Changes

1. Add Storybook
2. Create Stories for all docs components

TODO

1. create stories for all components
2. update CONTRIBUTING
   • make sure to run npm run build first
3. clean up any extra files
4. Update Greenwood Storybook guide
   • npm create requires an extra --, e.g. npm create storybook@latest --type web_components
   • storybook-addon-mock-fetch <> @storybook/preview-api incompatibility - Storybook 10 (and likely 9?) no longer uses @storybook/preview-api JohnAlbin/storybook-addon-fetch-mock#32
   • Vitest - just use Vite config w/ test field
5. running tests in storybook (nice to have)

This might be a little overkill for this repo (whole lot of extra deps), and ended up doing the upgrade as part of ProjectEvergreen/www.greenwoodjs.dev#272, so putting this into draft for now as reference.
