EntityFilter causing error with doctrine ORM 3.0

[BigMichi1]

Describe the bug
in some controllers i configure filters using the EntityFilter class similar to this one

public function configureFilters(Filters $filters): Filters
    {
        return $filters->add(EntityFilter::new('fireDepartments')->setLabel('entity.operation.fire.departments'))
            ->add(EntityFilter::new('operationType')->setLabel('entity.operation.type'))
            ->add(DateTimeFilter::new('operationDate')->setLabel('entity.operation.date'));
    }

when running my tests for this page where the filter is configured with an EntityFilter i'm getting

To Reproduce
configure an EntityFilter on a controller together with Doctrine 3.0 and EasyAdmin 4.9.0

same here.

EntityFilter doesn't not support ORM 3.0

``EasyCorp\Bundle\EasyAdminBundle\Filter\Configurator\EntityConfigurator::EasyCorp\Bundle\EasyAdminBundle\Filter\Configurator{closure}(): Argument #1 ($joinColumn) must be of type array, Doctrine\ORM\Mapping\JoinColumnMapping given`

Closing as fixed in #6145.
