Geo Replication - Remove hardcoded data

What does this MR do?

Regression from !35788 (merged)
Fixes #247528 (closed)

Geo Replicables was created to be generic between different Replicable Types. There were a few leftover hardcoded pieces for our first implementation (Package Files). Now that we are added more types, the bug exposed itself.

We already had the generic property state.graphqlFieldName we just need to actually use it 🤦
