Rails version check

[safang99]

Since many assignments before the introduction of make_it_so have gemfiles with rails -> 5.2, when running bundle you may end up with rails 5.2.4.3 or whatever the most up to date 5.2 version is. Currently make_it_so runs a check in prerequisite_check.rb to ensure 5.2.3 is installed and if not prompts a user to uninstall and reinstall rails 5.2.3. If possible we could update the check to ensure a users rails version only starts with 5.2.
