Use ansible ruby role to install gems

We're running into issues installing gems using "gem install"
commands, due to missing/outdated ruby version. Instead, we should
use a third-party ruby role, which will install a specific version of
ruby, and as a bonus, can handle installing the specific gems we want
as well.
