    app: no generic comment when no revision comment set.
    
    After discussing with Schumaml and Houz on IRC, let's just drop the
    generic comment which may be confusing and is probably unecessary,
    especially now that I write the revision number (present and new ones).
    So let's just assume people understand that they should update, even
    when GIMP version stays the same (this was the case I was the most wary
    about, that people think the notification is an error as since they have
    the last version, they don't have to update GIMP).
    
    I hesitated to at least leave just the simple "It is recommended to
    update." sentence but after much hesitation, let's go with no generic
    comment at all. The download button by itself should suffice.
    
    Of course, when a specific revision comment is set in
    gimp_versions.json, it is still displayed.
    
    (cherry picked from commit 56ffa2fd110281eaa84b3faaf077b8efe1846bb0)
