EditGuesser is broken

[maaarghk]

When trying to follow the tutorial, EditGuesser throws the following error:

TypeError: Cannot read property 'resource' of undefined
useResourceContext in node_modules/ra-core/esm/core/useResourceContext.js:40
  37 |  */
  38 | export var useResourceContext = function (props) {
  39 |     var context = useContext(ResourceContext);
> 40 |     return props.resource || context;
  41 | };
  42 | 

EditViewGuesser in node_modules/ra-ui-materialui/esm/detail/EditGuesser.js:19
  16 | import { EditView } from './EditView';
  17 | import editFieldTypes from './editFieldTypes';
  18 | var EditViewGuesser = function (props) {
> 19 |     var resource = useResourceContext();
  20 |     var record = useEditContext().record;
  21 |     var _a = useState(null), inferredChild = _a[0], setInferredChild = _a[1];
  22 |     useEffect(function () {

I notice that EditGuesser was recently changed in #5728. In this commit, useResourceContext was also changed for props to be checked before props.resource is checked - i.e. props is made optional.

However, when merging #5730 the conflict was resolved improperly and useResourceContext is back to having props as required.
