Fixed markup in Upgrading RoR guide [ci skip]

There are two changes:
- Using <ruby> syntax for unicode character routes example instead of
  <tt> since it causes single quotes to be transformed into inverted
  commas. This makes this required change more eye-catching.
- Using <tt> for the j alias and related helpers as written in the
  documentation guidelines.
