fix(amazonq): keyboard navigation in "Create a new prompt" overlay #6738

## Problem
When a user selects "Create a new prompt", a mouse is required to 1)
select the prompt name input field and 2) click the Enter button. This
flow should be able to be completed with just the keyboard

## Solution
Autofocus prompt input field, and allow submit on Enter key press.
