This fixes the description of parameter `array $config` in file ConfigurationExtensionInterface.php by removing the extra `$config`.
GraphizDumper now displays unresolved parameters

Previously it would crash when given a container with an unresolved
parameter. This change will instead show the parameter name on the
final diagram, instead of the class name.
