[rubygems/rubygems] Improve bug report instructions

* Explicitly recommend copying full command output and not just the bug
  report template part.
* Include quadruple quotes in the "What actually happened section" and
  tell users to copy full command output inside. Hopefully quadruple
  quotes will make the error report information (which includes triple
  quotes itself) render fine by default.
* Avoid "actually" as per quality_spec.rb recommendation.
