    authPrompt: Remove colons from questions
    
    Unfortunately, the question that is displayed comes directly
    from PAM. It usually is just "Password:", which comes from
    pam-unix, but other questions can be set, usually with the
    colons, since they are crafted with a CLI workflow in mind.
    
    Manually drop the colons from questions asked by PAM. This
    is also done by the PolKit agent, which shows how the stack
    is fragile, but it's what we have for now.
