Describe the bug

I added the package @doc-blocks/shield-row to a brand new project and I noticed two things that were documented on the storybook page.

1. the file @doc-blocks/shield-row/dist/main.css is not available on the dist folder.
2. the export is not using the export default so it should be import { ShieldRow } from '@doc-blocks/shield-row'; instead of import ShieldRow from "@doc-blocks/shield-row"
