Restrict datagridBuilder type to class-string and add Template

Fix

ArgumentTypeCoercion - src/Builder/DatagridBuilder.php:135:78 - Argument 2 of Sonata\AdminBundle\Filter\FilterFactoryInterface::create expects class-string, parent type string provided (see https://psalm.dev/193)
        $filter = $this->filterFactory->create($fieldDescription->getName(), $type, $fieldDescription->getOptions());

And

Method Sonata\DoctrineORMAdminBundle\Builder\DatagridBuilder::getBaseDatagrid() should return Sonata\AdminBundle\Datagrid\DatagridInterface<Sonata\AdminBundle\Datagrid\ProxyQueryInterface> but returns  
         Sonata\AdminBundle\Datagrid\Datagrid<Sonata\DoctrineORMAdminBundle\Datagrid\ProxyQueryInterface>.

And I'm trying to solve other issue in sonata-project/SonataDoctrineORMAdminBundle#1421
