**I'm not sure if this should be for the 6.4 or 7.4 branch**
**I'm not sure if this should be considered a bug or not**

This PR removes an unused `use` statement:

```php
use Symfony\Component\DependencyInjection\Attribute\Factory;
```
This class is not referenced anywhere in the file and does not exist in the current codebase, so it can safely be removed.
