    gdbusconnection: Clarify nullability in a documentation comment
    
    The comment previously said ‘never %NULL’, but it wasn’t clear whether
    this meant `(not nullable)` or `(not optional)`. From looking at the
    code, it means `(not optional)`.
    
    Clarify things by removing the prose. The annotations themselves should
    be clear and explicit enough.

    Closes: #1836
