fix: Autocomplete reset/re-render on keyboard events

[DafyddLlyr]

What does this PR do?

• Stops drop down list "resetting" to the top when an option is selected via keyboard

Context

Please see #2993 (comment)

Originally I had to nest ListboxComponent this within SelectMultiple in order to access functions related to the state of the popper.

What I think is happening is that selecting an item with they keyboard was causing a re-render of the popper and effectively resetting the view to the top of the list.

I've actually removed these here as currently clicking "Done" counts as a clickaway as it's outside of the scope of the popper (ref and props are applied to the role="listbox" child element within ListboxComponent). This actually in effect matches the current behaviour -

• there's no custom action being triggered by "Done" (just a close)
• it's already not keyboard navigable as a button

Before

After selecting an item, the focus shifts back to the first item
