title: VSTS Extension - Get build URL
body: <p>I'm developing a VSTS extension in Javascript. </p>
  
  <p>In one of my tasks, I need to get a link to my build results.
  I tried to read from {$Build.BuildUri} but it gives me <code>vstfs:///Build/Build/{buildId}</code> and not a real link.</p>
  
  <p>How can I get a direct link to my build results? I need it both in build and in release pipelines.</p>
