Command to run single quorum in raft is missing "--config" parameters.

When I run "bin/test-raft-server-start.sh config/raft.properties", I get an error：
[2020-11-14 23:00:38,742] ERROR Exiting Kafka due to fatal exception (kafka.tools.TestRaftServer$)
org.apache.kafka.common.config.ConfigException: Missing required configuration "zookeeper.connect" which has no default value.

The correct command is “ ./bin/test-raft-server-start.sh --config ./config/raft.properties”
