[solved] Machine name of Lesson content type is "quiz"

Hello, and thanks so very much for creating this distro of Drupal! I help a very small non-profit advocacy agency that runs free online courses for advocates, and we are really excited about your work on Opigno. I noticed while initially testing a fresh install of Opigno that the machine name for the content type "Lesson" is "quiz". This doesn't sound right to me! FYI here's no "Quiz" content type. I wonder if I can update the machine name to read "lesson", and also if I am missing a "Quiz" content type. Since I am brand new to Opigno, I wanted to check in here before trying to re-install and see if I can replicate the behaviour. Thanks again, ever so much!
