Adding additional value to FulfillmentOrderAssignmentStatus

As of API version 2024-04, you can retrieve a subset of fulfillment orders which are assigned to locations owned by the app performing the request but have not been requested for fulfillment so far.

The assignment_status parameter in the assignedFulfillmentOrders query can now accept a value of FULFILLMENT_UNSUBMITTED for filtering in addition to the existing FULFILLMENT_REQUESTED, FULFILLMENT_ACCEPTED, and CANCELLATION_REQUESTED filter values.
