Unable to create non PaaS sample environment with sql server due to reference to invalid template

[tusv]

Describe the bug
Creating non-PaaS sample environment with sql server is failing with following errror.

New-AzResourceGroupDeployment: /home/my/fhir-server-samples/deploy/scripts/Create-FhirServerSamplesEnvironment.ps1:197
Line |
 197 |  New-AzResourceGroupDeployment -TemplateUri $sandboxTemplate -environm …
     |  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | 8:27:26 PM - Error: Code=InvalidContentLink; Message=Unable to download deployment content from
     | 'https://raw.githubusercontent.com/microsoft/fhir-server/master/samples/templates/default-azuredeploy-sql.json'. The tracking Id is
     | 'a8e0163d-bb4c-4440-a604-21df446fe750'. Please see https://aka.ms/arm-deploy for usage details.

Doesn't look like the template is valid since it doesn't exist at that location. It looks like we are supposed to use same template for both cosmos/sql but pass different values for parameters.

Code snippet
https://github.com/microsoft/fhir-server-samples/blob/master/deploy/scripts/Create-FhirServerSamplesEnvironment.ps1#L153-L158

#Template URLs
$fhirServerTemplateUrl = "https://raw.githubusercontent.com/microsoft/fhir-server/master/samples/templates/default-azuredeploy.json"
if ($PersistenceProvider -eq 'sql')
{
    $fhirServerTemplateUrl = "https://raw.githubusercontent.com/microsoft/fhir-server/master/samples/templates/default-azuredeploy-sql.json"
}
