missing `require jquery-ui/menu` from `jquery-ui/autocomplete.css`

I updated `jquery-ui-rails` from `5.0.5` to `6.0.0`.
Then `list-style-type: disc` appeared in autocomplete.
So I think `require jquery-ui/menu` required in `jquery-ui/autocomplete.css`.
It removed at https://github.com/joliss/jquery-ui-rails/commit/d504a40538fe5f7998439ad2f8fc5c4a1f843f1c .
