React-admin: ReferenceManyField having Datagrid inside should support sorting

[rkyrychuk]

What you were expecting:
ReferenceManyField having datagrid inside should support sorting

What happened instead:
Sorting is not working, console show warning in debug mode

Warning: Failed prop type: Invalid prop `currentSort` of type `string` supplied to `ReferenceManyFieldView`, expected `object`.

Steps to reproduce:
Any ReferenceManyField with Datagrid inside

Related code:
sortBy function from here support object, not string.
```ReferenceManyField.js
const { sort, setSort } = useSortState(initialSort);

But value passed from Datagrid.js is [string](https://github.com/marmelab/react-admin/blob/next/packages/ra-ui-materialui/src/list/Datagrid.js#L132) 
```ReferenceManyField.js
setSort(event.currentTarget.dataset.sort);

When datagrid is handled by list controller, it change current sort object. But here ReferenceManyField just pass value from datagrid
I don't know your code standards so I'm not proposing pull request, but my code ovveride that fix the problem looks like that:

add static function that change order in _ReferenceManyField.js_
```ReferenceManyField.js
const switchOrder = (order, defaultOrder) => order ? (order === "DESC" ? "ASC" : "DESC") : defaultOrder

create updateSort function in **ReferenceManyField** render 
```ReferenceManyField.js
const updateSort = useCallback(field => setSort({ field, order: switchOrder(sort.order, "DESC") }), [setSort, sort.order]) 

map it to ReferenceManyFieldView

return ( <ReferenceManyFieldView
      {...props}
      {...{
        currentSort: sort,
        page,
        perPage,
        setPage,
        setPerPage,
        setSort: updateSort,
        ...controllerProps,
      }}
    />)

Thanks! Would you mind making a pull request ?

It'd be awesome to have sort, pagination and filter work for datagrids in all multiple references components (ReferenceArrayField, ReferenceArrayInput and ReferenceManyField).
