DrugCentral external references being incorrectly mapped to biolink:same_as

[hodgesf]

During conversion of the DrugCentral JSON file into a KG JSON file (found here), all ID's in the external_id are being incorrectly mapped to biolink:same_as. They should instead be mapped to biolink:related_to

Proposed solution: one line change from EDGE_LABEL_BIOLINK_SAME_AS to EDGE_LABEL_BIOLINK_RELATED_TO

Will make this change and push to main now, but need to come back and verify this in the next build.
We will not be rebuilding to address this.
