We should update the planner task get command to use the beta graph endpoint as that provides us with a `priority' property.

The response payload is exactly the same except for two properties:

..
     "priority": 5,
.. 
            "creationSource": {
                "teamsPublicationInfo": null
            }
.. 

We should update the documentation as well. As discussed in #3034 the implementation should be so that all calls keep using the v1.0 endpoint and we introduce an extra call that calls beta. The extra call then should get the new 'priority' property and merge that into the v1.0 results. We should update the documentation with a remark explaining what we do.
