    Add: a footer link to report a bug in GIMP
    
    We regularly get issues with GIMP in our gimp-help issue tracker.
    Let's add a link to GIMP's issue tracker. This might make it more clear
    to user's where to report issues.
    
    In addition to that:
    - Change links from http to https.
    - Update the text of the missing help page a bit.
    
    (cherry picked from commit f381e865798963633b89a7fbf4b42ac3cd95e2c0)
