Fix enter key loop in sweep commands (#7112)

* use effect for focus of command palette submit button, not autoFocus

autoFocus is being overridden by the Headless UI Dialog component's
focus management here
https://headlessui.com/v1/react/dialog#focus-management (we do not have
access to pass back initialFocus in this case). So we can use an effect
to imperatively focus the button when this component is mounted.

* Update sweep tests to submit the command with Enter
