The argument 'gatewayInstall.ps1' to the -File parameter does not exist

[101-vms-with-selfhost-integration-runtime](https://github.com/Azure/azure-quickstart-templates/tree/master/101-vms-with-selfhost-integration-runtime)

I'm using this template to provision Self-Hosted IR. As I understand, the template cannot be run locally, due to the linked templates and has to be run from an online location.
Hence, I changed the parameters in azuredeploy.parameters.json file and uploaded the entire template folder to the Azure Blob, which I provided the full read access

When I deploy the template via PowerShell using the following command

New-AzResourceGroupDeployment -ResourceGroupName -TemplateUri https://.blob.core.windows.net/deploy/shir/azuredeploy.json -TemplateParameterUri https://.blob.core.windows.net/deploy/shir/azuredeploy.parameters.json

I get the following error

Resource Microsoft.Compute/virtualMachines/extensions
'vm0-ir/vm0-irinstallGW' failed with message '{
"status": "Failed",
"error": {
"code": "ResourceDeploymentFailure",
"message": "The resource operation completed with terminal provisioning state 'Failed'.",

### Repro steps (*if necessary, delete otherwise*)
0. Create ADF and VNet services (include a new Subnet)
1. Download this template locally, and edit the parameters
2. Upload the template to a blob storage
3. Provide the readonly access to the blob container
4. Deploy from local PowerShell sesssion (ensure that you are logged to your Azure instance) as illustrated above, pointing to the template in blob
5. Observe the error as above

Inspect 101-vms-with-selfhost-integration-runtime/azuredeploy.json and its VM extension command, along with azuredeploy.parameters.json, to see how gatewayInstall.ps1 is made available when deployed from Blob storage. Reproduce with the listed New-AzResourceGroupDeployment command and confirm the extension completes without the missing-file error.
