body: <p>I'm starting to work with Azure and tried these steps:</p>
  
  <ul>
  <li>I added a secret to an Azure Vault.</li>
  <li>I linked a service principal to my Azure DevOps pipelines.</li>
  <li>I created a variable group linked to my vault.</li>
  <li>I created a variable group with some variables.</li>
  <li>I created a azure-pipelines.yaml with a variables: group: group1 group: group2 part</li>
  <li>I have <code>- task: AzureResourceManagerTemplateDeployment@3</code> with a template with parameters. How do I satisfy the paramters from the variable groups?</li>
