Update the OPA Version Bump Workflow to automatically run an OPA unit test and a smoke test with the new version

[buidav]

💡 Summary

This issue is to update the OPA version bump workflow to automatically download the latest version of OPA and run both an OPA unit test and a ScubaGear smoke test to see if there are any issues

Motivation and context

Currently a human still has to check that the latest OPA version isn't causing any issues to ScubaGear.
This update to the workflow will remove the extra work for the human. The humans will only need to check if the OPA unit test run and ScubaGear smoke test are working.

Implementation notes

• Updates to run_update_opa.yaml
• Likely requires refactoring run_update_opa.yaml to unit testable code as well.

Acceptance criteria

• An update OPA workflow includes information about a OPA unit test run with the new version and if a ScubaGear smoke test succeeded.
