[ruby/rubygems] Print help summary when the default command fail

As mentioned in https://github.com/ruby/rubygems/issues/9124,
the intent for changing the default command was to be more welcoming.

I think we can acheive that by attempting to install, but to print
that same help message if there is no Gemfile.

That should address both concerns.
