title: VS Code showing "type/arguments" in editor as labels
body: <p>I just installed VS Code 1.60.0-insider.</p>
  <p>At first I thought it was a bug, but now there are type/arguments hinds/labels in the editor:</p>
  <p><a href="https://i.stack.imgur.com/stty8.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/stty8.png" alt="enter image description here" /></a></p>
  <p>(<code>predicate:</code>, <code>callbackfn:</code>, etc.)</p>
  <p>How is this called and how to disable it? I searched online but couldn't find any information.</p>
  <p>Note: they only appear in TypeScript files.</p>
