Update performance.rst to use $container->getParameterBag()

[gnumoksha]

there is no $container->parameters()

[alamirault]

I think here $container is a ContainerConfigurator and not ContainerInterface

If i'm right, we should probably update example like is done in the following sample

symfony-docs/configuration.rst

Lines 375 to 383 in 19ca845

	.. code-block:: php
	// config/services.php
	namespace Symfony\Component\DependencyInjection\Loader\Configurator;
	return static function (ContainerConfigurator $container): void {
	$container->parameters()
	->set('url_pattern', 'http://symfony.com/?foo=%%s&bar=%%d');
	};

Friendly ping @gnumoksha

I've changed the variable name, but I don't know how to verify if the statement was successful.

I guess the whole example needs to look like this:

    .. code-block:: php

        // config/services.php
        namespace Symfony\Component\DependencyInjection\Loader\Configurator;

        return function(ContainerConfigurator $container): void {
            $container->parameters()->set('.container.dumper.inline_factories', true);
        };
