title: Github Actions: is there a way to make it mandatory for pull request to merge
body: <p>I am using a <strong>commitlint</strong> Github action to verify our commit messages.  Just wanted to check if there is a way I can make it mandatory to pass before merging pull request. </p>
  
  <p><strong>current behaviour:</strong> 
  commitlint github action fails, however, I can still merge the pull reqest </p>
  
  <p><strong>desired behaviour</strong> 
  if commitlint github action fails, button to merge pull request should be disabled. (i.e. like reviewer restriction) </p>
