github-actions[bot]storybook
This package provides a storybook build for Backstage. See http://backstage.io/storybook
Why is this not part of @backstage/core?
This separate storybook package exists because of dependency conflicts with @backstage/cli. It uses nohoist to avoid the conflicts, and since you can only use that in private packages it has to be separated out of @backstage/core.
