Since SERVER-53506 ReshardingDonorService/ReshardingRecipientService only update the coordinator if the coordinator document on the configsvr matches a predicate about the participants previously reported state.

If the update is stale, it doesn't occur.

For testing/ debugging purposes, it would be nice to log debug message when the update updates 0 documents (similar to what is done in the ReshardingCoordinatorService but logging instead of throwing since it is not a correctness issue)
