No reference withFakes in the doc

In the documentation explaint how to use Fake Fields but there is no reference to the function ->withFakes() that return the entity with fake fields as attributes. That makes it easier to display the information.
I think it would be good if, apart from explaining how to save, it would also explain how to retrieve the information.

Good thinking @adriallongarriu . I think we can add it to the API page - under All Operation - that would be the only place where this less-used method can be documented - https://backpackforlaravel.com/docs/5.x/crud-cheat-sheet#all-operations
