universal forwarder: scripts docker_service.sh contains invalid commands

[ghost]

I am pulling splunk/universalforwarder:7.0.0-monitor

and this is the content of the docker_service.sh script (the docker service ls command at the end of the file)

---

#!/bin/bash

DOCKER_BIN=$(dirname "$0")/docker "$DOCKER_BIN" service ls
| tail -n +2
| sed -e "s/,/ /g"
| sed -E "s/\s\s+/,/g"

docker service ls | tail -n +2 | sed -e "s/ /,/g"
