[gnome-boxes/wip/rishi/rhel: 3/17] wizard-source: Separate the groups of sources using headings

    wizard-source: Separate the groups of sources using headings
    
    This increases the height of the WizardWindow, so the WizardScrolled
    needs to scroll more aggressively.
    
    Note that the vertical height of the window is still more than what it
    used to be. That will be addressed in the following patch by moving the
    file selection button next to the heading label.
