      Deprecated.
      We need to override this as a LegacySerializerSnapshotTransformer because in Flink 1.6.x and below, this serializer was incorrectly returning directly the snapshot of the nested list serializer as its own snapshot.

      This method transforms the incorrect list serializer snapshot to be a proper ListViewSerializerSnapshot.
