Investigate a transition of Mod Workflow to the Spring Way

[jeremythuff]

Currently Mod Workflow is implemented in our own spring-module-core. In FOLIO most exisitng spring modules have been implemented using the EBSCO spring-way implemenation of spring: https://dev.folio.org/guides/spring-way/

We should identify what would need to be done to transition Mod Workflow to using the spring-way approach.

Sizing might be treated as part of linked issue if investigating both at the same time.
