Improved the code of an example

The original code contains an unneeded *"pop culture"* reference. For those unaware of it, it contains two strong words ("kill" and "bastard").

The concern about this example was firstly raised in the `#diversity` channel of [Symfony Slack](https://symfony.com/support).
