title: Is there a way to get the project folder name only on a Github action?
body: <p>I can get <code>repoowner/repo-name</code> with <code>${{ github.repository }}</code> but I like to get just the <code>repo-name</code>.</p>
  <p>While I am at it.</p>
  <p>GitLab has a straight forward variable for this.</p>
  <p>How do I get reference access env variables from the <code>.yaml</code> not inside scripts? Does <code>${{ $ENV_VAR }}</code> work? Probably not.</p>
  <p>Is there a way to remove or replace the slashes directly in the yaml?</p>
