Updates to the `DependencyValue` implementation

[rachelatmonday (Rachel)]

We recently updated the DependencyValue implementation, so you can now return both the linked_items and the linked_item_ids for dependency columns when querying through column_values V2.

Please note that the DependencyValue implementation is only available in version 2023-10.

query {
  items (ids:[1234567890, 9876543210]) {
    column_values {
      ... on DependencyValue {
        linked_item_ids
        linked_items
      }
    }
  }
}
