GIVEN I am viewing the settings page on the Annotations tab
WHEN I click the blue Add Annotation Stream button
THEN an overlay appears with a form for creating an Annotation Stream

Design Mockup
CreateAnnotationStreamOverlay.tsx

NOTE: Some of this UI is built out already

• See the overlay by clicking the add button or by visiting /settings/annotations/new

GIVEN I am adding an annotation stream
WHEN I click the blue Add Annotation Stream button
AND the name input is empty or the query is incomplete
THEN I see errors explaining how to resolve

Technical note:

Since this UI re-uses some flows components (in addition to a special cell type for annotation streams) there is some de-risking to do here
