GitHub workflow refactor

[Gordonby]

Some routine maintenance is stacking up for the Workflows.

1. Move to latest versions of GitHub actions for things like Azure login, Artefact upload (see Node 12 deprecation warning)
2. Add generic ingress support to the Azure Vote reusable workflow
3. Rip out and replace the "simple app deployments" with the Azure Vote reusable workflow
4. Move to the latest version of the Azure CLI
5. Stop using set-output and move to the newer way (see deprecation notice)
6. Make Cleanup a reusable workflow
7. Move to Azure Federated Credentials for all workflows
8. Run the OSS workflow on PR (once all 3 deployments can run concurrently)
9. Check for latest AKSC release version in the OSS workflow instead of hardcoding
10. Don't wait for cleanup to report workflow success in InfraCI - Starter cluster / Cleanup (pull_request)
11. Opt out of deployment telemetry for all CI/CD workflows
12. Refactor workflows that use cleanup to target the new workflow
14. Check for latest AKSC release version in the OSS workflow instead of hardcoding
