chore: remove deprecated orm package

[ryanchristo]

Description

The orm package is no longer maintained and no changes that affect the group module have been made since the release of v1.0.0-beta1. This pull request removes the orm package and updates the group module to use v1.0.0-beta1 (the ecocredit module is already using v1.0.0-beta1, which is needed for state migrations).
