Upgrade to Rails 5.x or 6.x?

Hi @kalmanh,

Thanks for the course, it is great indeed!
However, it appears that if the system has Ruby 2.7 installed then it becomes a huge pain to get this running. Cloning this and running rails s should give you an idea (but I am sure you'd know already!).

Therefore, it'd be best if the grader and this part of the course could you later versions of Ruby (2.7.x) and Rails (5.x or 6.x -- the later the better!).

This should ensure things to run smoothly and the participant/student could actually focus on building things instead of just running circles, setting up the environment (which is very painful with Rails 4.x).

I could send you a patch to update Gemfile, Gemfile.lock, and config/application.rb.
But this has to be done on the grader side, too, I think. It is using older versions which gets logged on STDERR as well.
