[rubygems/rubygems] Fix another strange error when running bundle add in frozen mode

If there's a lockfile, but it's out of sync with the Gemfile because a
dependency has been deleted, and frozen mode is set, Bundler will print
the following strange error:

$ bundle add rake , but the lockfile can't be updated because frozen mode is set You have deleted from the Gemfile: * rake (~> 13.2) Run `bundle install` elsewhere and add the updated Gemfile to version control. 

This commit changes the error to:

Some dependencies were deleted from your gemfile, but the lockfile can't be updated because frozen mode is set You have deleted from the Gemfile: * rake (~> 13.2) Run `bundle install` elsewhere and add the updated Gemfile to version control.
