    Revert "build: bump WebKitGTK+ dependency to stable version"
    
    This reverts commit fde8ce18b892e8218d7773724d410a4ef301fa7d.
    
    I bumped the version because I prefer to specify stable versions. But it
    was probably too early, I've got one complain for gnome-builder on
    aarch64/arm because it rarely is up to date that quick with webkit on
    that architecture.
    
    2.19.2 is required for webkit_settings_font_size_to_pixels() (at least).
