[Bug] Improper enum value comparison on workflow update

[cretz]

Describe the bug

Error with trace:

ArgumentError: comparison of Symbol with 2 failed (ArgumentError)
               resp.stage >= Temporalio::Client::WorkflowUpdateWaitStage::ACCEPTED
                             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Basically, per https://protobuf.dev/reference/ruby/ruby-generated/#enum enums inside protos may be symbols instead of integers, so we were improperly comparing as if it was an integer. We may need to change the LHS to something like Api::Enums::V1::UpdateWorkflowExecutionLifecycleStage.resolve(resp.stage)
