    core.learn: Use LaunchAgain by default for terminals
    
    Set a default config that uses Launch Again as default action for
    gnome-terminal and xfce4-terminal. This is injected if no default
    actions have been stored in the config before (i.e. new users and
    those upgrading Kupfer.)
    
    It is possible to undo just like if manually configured (setting
    default again or using forget).
