Documentation: improve Verified label configuation section

* Adjust documentation to state that the Code-Review label is the only
  actual default configured label.
* Add `copyAllScoresIfNoCodeChange = true` to example Verified label
  configuration to mimick what the InitLabels InitStep would configure.
