Jest throws DND Draggable warnings

[drewdaemon]

This is to document that this react-beautiful-dnd issue exists in this library as well.

In Kibana, we are currently employing this strategy atlassian/react-beautiful-dnd#1593 (comment) to suppress the messages.

Except, since we are switching to this library, the correct flag is

window['__@hello-pangea/dnd-disable-dev-warnings'] = true;
