feat: use new IDiagnostic type [SL-2125] (#45)

BREAKING CHANGES: The diagnostics interface has changed and the `show` now shows fields instead of hides them.


* feat: use new IDiagnostic type

* chore: storybook v5

* fix: summary should be consumed

* chore: remove @emotion/core

* feat: less TypeScript-ish

* fix: show means show, not hide
