Unable to use `Examples` attribute

I recently updated to codeception v5 - which works like a charm 😊
I just wanted to try out the new `Examples` Attribute. Unfortunately I get this:

```php
use Codeception\Attribute\Examples;
use Codeception\Example;
use Symfony\Component\HttpFoundation\Response;
use Tests\Support\FunctionalTester;

final class LegacySeriesRedirectControllerCest
{
#[Examples(url: '/de/series/index', expected: 'asdf')]
public function foo(FunctionalTester $I, Example $example): void
{
$I->followRedirects(false);
$I->amOnPage($example['url']);
$I->seeRedirectTo($example['expected'], Response::HTTP_FOUND);
}
}
```

```
LegacySeriesRedirectControllerCest: Foo
Test tests/Functional/App/Controller/Frontend/LegacySeriesRedirectControllerCest.php:foo

[InjectionException] Failed to inject dependencies in instance of 'Functional\App\Controller\Frontend\LegacySeriesRedirectControllerCest'. Failed to create instance of 'Codeception\Example'. Parameter 'data' must have default value.

According to #867 this should work. What am I doing wrong?
