Fixes error on module installation:

Fatal error: Declaration of Drupal\jsonapi_schema\Normalizer\DataDefinitionNormalizer::normalize($entity, $format = null, array $context = []) must be compatible with Symfony\Component\Serializer\Normalizer\NormalizerInterface::normalize(mixed $data, ?string $format = null, array $context = [])
