Valkyrize HykuUp: run migration script

[ShanaLMoore]

Summary

After the valkyrized app has been deployed to production, we could run a script to migrate records instead of relying on lazy migrations.

"This script allows you to run a lambda on every instance of works, collections, etc in a resumable way. Very useful for migrating from Fedora to Postgres using Valkyrie." - Kiah
