title: Create pull request with github action
body: <p>I'm trying to make it work this action, but I'm confused also whats it's missing in between, before triggering the peter-evans PR.</p>
  <p>The scenario is pretty simple, I like on push, on any feature/* branch, to create automatically PR, but instead I'm getting weird scenario, where develop changes are applied on top of the feature/* branch. Can someone give me hints on this?</p>
