docs: // NewLineage generates a new lineage identifier string. A lineage identifier
  // is an opaque string that is intended to be unique in space and time, chosen
  // when state is recorded at a location for the first time and then preserved
  // afterwards to allow Terraform to recognize when one state snapshot is a
  // predecessor or successor of another.
