Remove test environment from suggested Gemfile code.
Remove test environment from suggested Gemfile code.

If the Gemfile's involved, it's likely a standard requirement for all tests (and from a gem development perspective, that env is 'development' - matching `add_development_dependency` in the gemspec). The `development` label is unrelated to the development/test/production trio from a standard Rails app.
