    gvariant: Fix some typos in documentation
    
    Reformatted the docs for G_VARIANT_TYPE_UINT64 to avoid having a
    number in the beginning of the line, because apparently gtk-doc treats
    that as a first element of the numbered list. The number being that
    big probably makes gtk-doc to treat it as 1.
    
    Fixed the g_variant_new_fixed_array documentation - it was partially
    copy-pasted from the g_variant_get_fixed_array documentation.
    
    The rest should be quite obvious.
