I guess this can't be snake case because it was already like this in the other SDKs? Do we already have released versions with it like that? Otherwise it'd be good to make them all snake case since that's more standard

Yeah and the other two ones for workflows are NonDeterminismError and WorkflowError and those not snake case

If the workflow task failure is due to gRPC message too large, set GrpcMessageTooLarge as
failure_reasonontemporal_workflow_task_execution_failed.closes #1065
Note
Adds a specific failure_reason label GrpcMessageTooLarge to workflow task failure metrics when WFT completion hits an oversized gRPC message and records the metric.
