RDS Deployment to existing AD failing

Azure Quickstart Templates\rds-deployment-existing-ad (https://raw.githubusercontent.com/Azure/azure-QuickStart-Templates/master/rds-deployment//Configuration.zip)

### Issue Details
Details for below path come from azuredeploy.json (lines 110, 451, 534, and 616)

Getting the following error when running the deployment.

"VM has reported a failure when processing extension 'gateway'. Error message: \\\"The DSC Extension failed to execute: Error downloading https://raw.githubusercontent.com/Azure/azure-QuickStart-Templates/master/rds-deployment//Configuration.zip after 29 attempts: The remote name could not be resolved: 'raw.githubusercontent.com

Please note the double forward-slash before the Configuration.zip file name. I don't know if this is correct or not. I don't know enough about JSON files and their syntax to be sure. If this was a normal Internet path address that would be wrong.

Inspect azuredeploy.json at lines 110, 451, 534, and 616, along with the rds-deployment-existing-ad template path and Configuration.zip URL. Verify whether the double slash produces the reported download failure, correct the deployment reference if needed, and confirm the existing-AD deployment no longer reports the gateway DSC extension error.
