title: Docusaurus V2 remove version label from doc pages
body: <p>In each page of docs the label <code>Version: Next</code> is visible:</p>
  <p><a href="https://i.stack.imgur.com/TXxCR.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/TXxCR.png" alt="screen of that label" /></a></p>
  <p><strong>Is there a way to disable and remove the label?</strong></p>
  <p>Since I don't want to add multiple versions to my documents, I don't need the label.</p>
