Why are these changes needed?
Duplicate for #25247.
Adds a fix for Dask-on-Ray. Previously, for tasks with multiple return values, we implicitly allowed returning a dict with the return index as the key. This was used by Dask-on-Ray, but this is not documented behavior, and we now require task returns to be iterable instead.
