title: using yq to get keys and a specific value without knowing key names
body: <p>I have a .yml file structured like this</p>
  <pre><code>key_1:
     some_other_key
     owners: value
  key_2:
     some_other_key
     owners: value
  key_3:
     some_other_key
     owners: value
  </code></pre>
  <p>I am trying to get the top level key and the value of owners so the output is like</p>
  <pre><code>key_1, owners.value
  key_2, owners.value
  key_3, owners.value
  </code></pre>
  <p>Is there a way to do this with yq?</p>
