Allow Comment in OpcPublisher Configuration when Validation is used

[bqstony]

Actualy when i use the the Validation on startup in the opc-publisher container then i get a error when my publishernodes.jsonc has commends inside.

this is a sample to start my container:

docker run -it --rm --name opcpubtest -v /mnt/c/source/publisherconfig:/mount/publisherconfig --env "EdgeHubConnectionString=secret" mcr.microsoft.com/iotedge/opc-publisher:2.8.3 --publishfile=/mount/publisherconfig/publishednodes.jsonc --publishfileschema=/mount/publisherconfig/strict-publishednodesschema.json --opcpublishinginterval=1000 --autoaccept --logfile=/mount/publisherconfig/publisher.log --messagingmode=PubSub --batchsize=100 --iothubsendinterval=1 --heartbeatinterval=3600

the configuration file publishednodes.jsonc looks like

// This file configures the XXX-OPC UA Server nodes
// It requires at least mcr.microsoft.com/iotedge/opc-publisher:2.8.3
/* some more header comment */
[
  {
    // Example for an EndpointUrl is: opc.tcp://192.168.178.26:62541/Quickstarts/ReferenceServer
    "EndpointUrl": "opc.tcp://10.10.1.152:48040",
    // Allows to access the endpoint with SecurityPolicy.None when set to false (no signing and encryption applied to the OPC UA communication), default is false.
    // Controls whether to use a secure OPC UA mode to establish a session to the OPC UA server endpoint.
    "UseSecurity": true,
    // Enum to specify the session authentication. Options: "Anonymous", "UsernamePassword"
    "OpcAuthenticationMode": "UsernamePassword",
    // The username for the session authentication. Mandatory if OpcAuthentication mode is "UsernamePassword".
    "OpcAuthenticationUsername": "xxx",
    // The password for the session authentication. Mandatory if OpcAuthentication mode is "UsernamePassword".
    "OpcAuthenticationPassword": "xxx",
    // The data set writer group collecting datasets defined for a certain endpoint.
    "DataSetWriterGroup": "Asset0",
    // The unique identifier for a data set writer used to collect OPC UA nodes to be semantically grouped and published with the same publishing interval.
    "DataSetWriterId": "DataFlow0",
    // The DataSet collection grouping the nodes to be published for the specific DataSetWriter defined above.
    "OpcNodes": [
      {
        "Id": "nsu=http://microsoft.com/Opc/OpcPlc/;s=Events.Alarm.Class",
        "DisplayName": "Class"
      },
      {
        "Id": "nsu=http://microsoft.com/Opc/OpcPlc/;s=Events.Alarm.Code"
      },
      {
        "Id": "nsu=http://microsoft.com/Opc/OpcPlc/;s=Events.Alarm.IncomingUTC"
      },
      {
        "Id": "nsu=http://microsoft.com/Opc/OpcPlc/;s=Events.Alarm.Message"
      },
      {
        "Id": "nsu=http://microsoft.com/Opc/OpcPlc/;s=Events.Alarm.OutgoingUTC"
      },
      {
        "Id": "nsu=http://microsoft.com/Opc/OpcPlc/;s=Events.Alarm.State"
      },
      {
        "Id": "nsu=http://microsoft.com/Opc/OpcPlc/;s=Events.Alarm.Unit"
      }
    ]
  }
]

This will result in an error to load the configuration.
