Acceptance criteria

Update the Combobox portion of the Usage, Style, and Accessibility tab docs to reflect the new behavior of entering a unique value.

Usage tab

Combobox

### Unique value

• Add a new H3 section heading for entering a unique value. Initial ideas for this name is "Unique value", "Entering a unique value".
• Add new content and images.

Universal behaviors

Interactions

Keyboard

Combobox:

• Add some written guidance on how to handle keyboard interactions for this if needed in the combobox section.

Style tab

• Unique value: As far as I can tell, there are no visual differences we need to address on the Style tab for entering a unique value right now, it is more of interaction changes? Need to double check
• Eventually there will be an exploration/design spec for improving the visuals of this experience in this umbrella.
