REVISION SUMMARY
  The runners are loaded from the plugin info list `Plasma::RunnerManager::listRunnerInfo()`,
  because of that there is no need to create a RunnerManager and initialize the plugins.
  
  If you have a lot of additional plugins installed that do a lot of work in the init/reloadConfiguration
  method the loading time of the KCM is notable slower.
  
  Additionally the KCMUTILS_VERSION version check has been removed, because
  the KF5_MIN_VERSION is 5.69.

TEST PLAN
  All plugin should show up.
  To check this create a debug which prints the length of the `listRunnerInfo` list.
  Then you can verify that the length of the list is equal to the count
  of entries in the plugin selector. For this you can also use the xdotool utility:
  `sleep 5;for i in {1..myNum};  do sleep 0.1;xdotool key Down; done`.
