Title: Fix an incorrect configuration snippet in the cookbook about scopes

Pointed out by stof [here](https://github.com/symfony/symfony-docs/pull/2343#discussion_r3536554).
When using `['@?request']]` the synchronized service does not work and I get a `ScopeWideningInjectionException`. Using `['@?request=']]` fixes that issue.
