Changelog for @canva/intents

• Adds a new field contentNoun to content publisher intent, which controls the copy of the publish button. Leaving it empty defaults it to type 'content' (generic). Consumers should set this appropriately and prepare for the deprecation of custom overrides (the current method of changing the publish button copy).

• The DocumentPreview union now includes upgrading and ready states in the GA package

• Add design metadata in MediaSelections
• Enable apps to support transparent PNG exports in publish flow by adding optional allowTransparentBackground capability to ImageRequirement

• Launch the new Email media type to public, enabling publishing and selection of email pages.

• Re-export data types from the intents/data public API that were accidentally removed during a refactor
• Rename Selection type to MediaSelection for clarity

• Promoted Selection, ImageSelection, VideoSelection, DocumentSelection, EmailSelection types and MediaSlot.selection field from beta to public
