title field is considered as base field in Drupal 8, I opted
hook_entity_base_field_info_alter to add validation to it. But when I look at that hook.
hook_entity_base_field_info_alter(&$fields, \Drupal\Core\Entity\EntityTypeInterface $entity_type)
It doesn't holds a
$bundle argument. So I couldn't add a validation for title field of a particular node type. How can I override it to be node type specific?
