Enhance PDS3 metadata to include references to PDS4 context products

[jordanpadams]

💡 Description

In order to support new web mod website search, we need to be able to link based upon investigation_ref, instrument_ref, target_ref, etc. Current PDS3 context products do not link to that. We need to update those to support that.
