title: Azure DevOps Service Connections restriction not applying to Release Pipelines
body: <p>I have setup a Service Connection and I don't want the connection to be used by all pipelines. So I have left the <code>Grant access permission to all pipelines</code> checkbox unchecked.
  But this seems to have no effect on Release Pipelines. Connection is visible and available for all of them.
  Is this checkbox only intended for YAML pipelines? Is there a way to allow using connections to only specific releases?</p>
  
  <p>This is not an Azure connection</p>
