101-vms-with-selfhost-integration-runtime - template resource '_artifactsLocation' at line '81' and column '27' is not valid

[101-vms-with-selfhost-integration-runtime](https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/101-vms-with-selfhost-integration-runtime/azuredeploy.json)

### Issue Details
I was reading [a blog about setting up a SHIR for connecting data factory to an SQL database within a VNET](https://towardsdatascience.com/how-to-secure-your-azure-data-factory-pipeline-e2450502cd43) and encountered a problem when trying to set up the SHIR.
### Repro steps (*if necessary, delete otherwise*)
1. Section 3b of the linked article has the following command:
`az group deployment create -g $shir_rg --template-uri https://raw.githubusercontent.com/Azure/azure-quickstart-templates/master/101-vms-with-selfhost-integration-runtime/azuredeploy.json --parameters existingDataFactoryName=$adfv2 existingDataFactoryResourceGroup=$rg existingDataFactoryVersion=V2 IntegrationRuntimeName=$shir_name NodeCount=2 adminUserName=$shir_admin adminPassword=$shir_pass existingVirtualNetworkName=$vnet existingVnetLocation=$loc existingVnetResourceGroupName=$rg existingSubnetInYourVnet="shir"`

The command fails when using Azure CLI 2.3.0 with the following error:
`{'additional_properties': {}, 'code': 'InvalidTemplate', 'message': "Deployment template validation failed: 'The template resource '_artifactsLocation' at line '81' and column '27' is not valid: The language expression property 'uri' doesn't exist, available properties are '$schema, contentVersion, parameters, variables, resources'.. Please see https://aka.ms/arm-template-expressions for usage details.'.", 'target': None, 'details': None, 'additional_info': []}`

Start with 101-vms-with-selfhost-integration-runtime/azuredeploy.json, especially the resource named _artifactsLocation around line 81. Reproduce the deployment using the Azure CLI command and parameters in the issue, then inspect the template expression validation error. Done means the template validates and the self-hosted integration runtime deployment proceeds without this error.
