react-dnd should be in dependencies, not devDependencies

<DragDropContextConsumer>

Because of this line, react-dnd should be in dependencies, not devDependencies.

In my project I have "react-dnd": "^7.0.2" and I saw no error/warning that frontend-collective-react-dnd-scrollzone depends on "react-dnd": "^7.3.0". And only when I launched the project, I saw in dev tools that react-dnd doesn't export DragDropContextConsumer.
