This compiler pass finds all services tagged with overblog_graphql.definition_config_processor and injects them into the ConfigProcessor service. The same thing can be done with the !tagged_iterator flag, so it's not necessary to do it manually. This PR removes the ConfigProcessorPass:

class ConfigProcessorPass implements CompilerPassInterface	
{	
    public function process(ContainerBuilder $container): void	
    {	
        $definition = $container->findDefinition(ConfigProcessor::class);	

        $taggedServices = $container->findTaggedServiceIds('overblog_graphql.definition_config_processor');	

        $arguments = [];	
        foreach ($taggedServices as $id => $tags) {	
            $arguments[] = new Reference($id);	
        }	

        $definition->setArgument('$processors', $arguments);	
    }	
}
