    app: allow to disable the new version check altogether through a key…
    
    … in the gimp-release file.
    
    This will be useful to disable the update check for the Windows Store
    even though we use the same build as the installer. All it will take
    will be to append the line `check-update=false` to the file
    `share/gimp/2.10/gimp-release` and it will behave as though the update
    check is disabled (even though it is actually built-in).
