Subject: [PATCH] Add pry-byebug gem to Gemfile

I occasionally want to use pry-byebug when debugging.
This PR adds pry-byebug to Gemfile.
https://github.com/deivid-rodriguez/pry-byebug

pry-byebug (3.6.0) requires MRI 2.2.0 or higher.
https://github.com/deivid-rodriguez/pry-byebug#requirements

So this implementation will switch installation by conditional branch.
We can remove this conditional branch in the future when RuboCop drops
supporting Ruby 2.1.
