Fix `ci_usage_warning_message` message builder

Description

@rspeicher

This is the first thing I see after creating a new project on gitlab.com -- something hitting me up for purchase without describing what it is or why I need to do it?

Analysis

The issue is with this line then https://gitlab.com/gitlab-org/gitlab/blob/561fd235d6bb8a8ada2351cc24ff9b72cfe7881e/ee/app/helpers/ee/runners_helper.rb#L7 Previously message was a string, so this check was good, but it looks like message became an array recently so this check is no longer valid.
