[rubygems/rubygems] Remove `gem install` hint when installing a gem fails

A fresh `gem install` might not reproduce the exact `bundle install`
environment that originally caused the error. It also makes it harder
for the user to troubleshoot the error since she needs to run a separate
command.

Instead, show the original error and backtrace directly.
