    Enable webkit sandbox on GApplication.startup
    
    This needs to be done only once, so this is a good place for it.
    
    In commit 3fcb670f7385 we enabled it using Gjs "static" syntax, which
    is not available in Gjs versions older than 1.71.1.
    https://gitlab.gnome.org/GNOME/gjs/-/blob/70552bee79f644836a5e9f9a54845791b1ef7a94/NEWS#L67
    
    Let's enable it on GApplication.startup for GNOME 41.
    
    Fixes #81
