Research the update deployment_rollback ALLOWED_USERS list to group

[emvaldes]

The GitHub Workflow "deployment_rollback" is still hardcoded in the ALLOWED_USERS variable to: ./.github/workflows/deployment_rollback.yml:18: ALLOWED_USERS: "lucasdze,jeremy-page,JosiahSiegel,snesm,supriyaaddagada"

Note: We should/must change this approach and base it on GitHub Groups. Unless, this is not possible so that next time we do not need to create a change. Are these hardcoded because of the way this workflow requires these to be setup?

I am recommending to change it to something like: ${{ env.ALLOWED_USERS }}
