Wrong documentation for the BatchOperation task

[visma-dinei-rockenbach]

The documentation for the BatchOperation task (here) that is shown inside Frends' interface states that the Task's result includes a JToken Data field, which is incorrect (as one can see in the definition of the Result class).

Thus, those who rely on the documentation shown in Frends' interface to use the task are misled, and requires the users to check the source code to understand what is happening under the hood.
