[Scheduler] Add example about how to pass arguments to a Symfony command

We recently wanted to pass arguments to a Symfony command which is configured for the scheduler component with the `#[AsPeriodicTask]` attribute.

The syntax mentioned in symfony/symfony#51525 (comment) worked.
This PR adds an example to the docs.
