Issue Description:

On this page: https://fdc3.finos.org/docs/next/agent-bridging/ref/broadcast

The example is:

// agent-A -> DAB
{
    "type": "broadcastRequest",
    "payload": {
        "channelId": "myChannel",
        "context": { /*contextObj*/ }
    },
    "meta": {
        "requestUuid": "<requestUuid>",
        "timestamp": "2022-03-...",
        "source": [{
            "appId": "agentA-app1",
            "instanceId": "c6ad5174-6f78-4582-8e96-728d93a4d7d7"
        }]
    }
}

NB: Source is an array.

However here https://fdc3.finos.org/assets/files/broadcastAgentRequest.schema-ae49cce8b8e358ec2b04033bc8570357.json it is not.
