Registry and npmjs access for quiz
    
    1. container uses BCI (in registry.o.o, we only have Tumbleweed based
      BCIs)
    2. os-web is already entered in GitHub ACL, but jump to chain was
       missing
    2. container builds off Git and pulls JavaScript dependencies during
       build (not pretty, but vendor => package => container flow was
       considered as too slow for fast updates during conferences, and
       ultimately JS vendoring would be similar, just from another machine)
