Drag and drop should not be constrained to the handle only

In ranking tasks, drag and drop should not be constrained to the handle only, but should be the entire text element.

I suggest we make sure to keep the drag handle icon so that it is still clear than it can be dragged (and after this change will also be easy to use)

Also this element is interacted with in the end-to-end tests so make sure to run npm run cypress:run or npm run cypress (from the /website folder, and with the website running at localhost:3000 ) to check that those still pass.

This is now already implemented.
