fix: consume type compatible with protocol

[ahjdzx]

通过 mqadmin consumerStatus 查看消费者状态时，命令执行失败。

$ NAMESRV_ADDR=localhost:9876 sh bin/mqadmin consumerStatus -g testGroup                                                                                                                                   (rocketmq-all-4.5.2*) 13:37:07

修改 ConsumeType 常量值后解决。
