Include resource ID in OAV validation response

[wwendyc]

In the OAV validation response, include the resource ID if it's available to make it easier for RPs to tell which resources require fixing.

Example of what's currently returned for a LIST GET in the validation error results:

{
  "isSuccessful": false,
  "operationInfo": {
    "operationId": "SqlServerInstances_List",
    "apiVersion": "2021-11-01"
  },
  "errors": [
    {
      "code": "INVALID_TYPE",
      "message": "Expected type string but found type null",
      "source": {
        "url": "specification/azurearcdata/resource-manager/Microsoft.AzureArcData/stable/2021-11-01/sqlServerInstances.json",
        "jsonRef": "#/definitions/SqlServerInstanceProperties/properties/containerResourceId",
        "position": {
          "line": 59,
          "column": 32
        }
      },
      "documentationUrl": "",
      "pathsInPayload": [
        "/value/4/properties/containerResourceId",
        "/value/5/properties/containerResourceId",
        "/value/6/properties/containerResourceId"
      ],
      "jsonPathsInPayload": [
        "$.value[4].properties.containerResourceId",
        "$.value[5].properties.containerResourceId",
        "$.value[6].properties.containerResourceId"
      ],
      "schemaPath": "#/properties/containerResourceId/type"
    }
  ]
}
