Improve CI

- [X] ensure tests are run (e.g. `common`)
- [ ] ensure that `make build-package` in `github-action` doesn't result in changes (i.e. enforce that it has been run) (#80)
- [ ] ?Split the azdo test into a [triggered pipeline](https://docs.github.com/en/actions/reference/events-that-trigger-workflows#workflow_run) and [tag with an environment](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idenvironment) (require approval)
- [x] Add docker-from-docker test for GH action
- [x] Add docker-from-docker test for AzDO task
- [ ] Make AzDO pipeline project public (waiting on being granting build pipeline execution)
- [ ] show the AzDO pipeline run as a [check on the PR](https://docs.github.com/en/rest/reference/checks)
- [ ] explore ways to ensure that only a single instance of the AzDO publish VSIX + run build is running at once (maybe less relevant if split and requires approval)
