Better wording for error message "Default Root"

[samuells]

The issue occurs while working with: (check one with "x")

• [x] app.storyblok.com (CMS - Interface)
• [ ] api.storyblok.com (CMS - Content Delivery API)
• [ ] mapi.storyblok.com (CMS - Management API)
• [ ] capi.storyblok.com (Commerce - API)
• [ ] Commerce - Interface
• [ ] Other:

Current behavior: This is the current wording of the error.

Expected behavior: I would expect to point out that it should be setup in Settings > General Tab.
