Review Comment:
I think the `connectorAssignments` should be equal to
`diff(connectorAssignments, revokedConnectors)` and `taskAssignments ==
diff(taskAssignments, revokedTasks)`, because in L279:
https://github.com/apache/kafka/pull/11983/files#diff-e24067b121eb960feebfa099bd9c30382e330eaf5db39302a9d7a50e29b3acb4R279-R283
We already removed the revoked connectors/tasks. Is my understanding correct?
