Using deprecated attribute in deprecated `trait` is not silenced

```php
/**
 * @deprecated
 */
trait SomeTrait {
    #[SomeDeprecatedAttribute]
    public mixed $field = null;
}

/**
 * @deprecated
 */
abstract class ClassUsingTrait {
    use SomeTrait;
}
```

gives `Attribute class SomeDeprecatedAttribute is deprecated.`
