Feature Design - Change response structure to simplify `hits.edges.nodes`

[joneubank]

Detailed Description

The use of hits.edges.nodes is cumbersome and unnecessary, and definitely confusing especially for new devs. This is a relic of an old recommendation for GQL response structure.

We would like to propose a new response structure and use the upcoming release of Arranger 3 to use the new structure. This ticket is a stub to provide a place to document and discuss a new alternative approach.
