json syntax errors in cb_cmds hook documentation examples

There are error(s) in some of the example code blocks in https://kea.readthedocs.io/en/latest/arm/hooks.html#cb-cmds-configuration-backend-commands

EXAMPLE: There is a missing ',' like so:

{
    "command": "remote-server6-get"
    "arguments": {
        "servers": [
            {
                "server-tag": "server1"
            }
        ],
        "remote": {
            "type": "mysql"
        }
    }
}

There should be a comma after "command": "remote-server6-get" but there is not in the ARM under https://kea.readthedocs.io/en/latest/arm/hooks.html#the-remote-server4-get-remote-server6-get-commands
