Ensure that Azure Files are used for Azure App Service

Azure App services do not use Azure Files, this may lead to data loss due to low resilience.

In Azure Console -

1. Open the Azure Portal and go to App Services.
2. Select the App service you wish to edit.
3. Select Configuration under Settings.
4. Select the Path mappings tab.
5. Create a new storage mount and set it to use Azure Files. Configure as needed.

In Terraform -

1. In the azurerm_app_service resource, create a storage_account block.
2. Set storage_account.type to AzureFiles.
