In the dashboard under Templates -> <Template> -> Versions, users with the member role may view, but not click, the "Promote" button to set an active version for a template. They can click anywhere in the version listing; when they do, it returns a 404.

In general, there's no reason for developers to see the versions page as they are not managing template status. Thus, we should hide the "versions" section entirely and redirect non-template-admins when they navigate here directly.
