CI: Notifications when a job in GitHub Actions fails
xref #32279

For what I see, when a build in the CI for a commit to master fails, only the user who triggered the action receives an alert (assuming the user has notifications enabled in [their settings](https://github.com/settings/notifications#github-actions-heading)).

I think for Travis and pipelines, some people are receiving notifications for all the failures. Ideally we would like to be able to do the same for actions. I had a quick look, but not sure how this can be enabled. I checked in the settings, but no option seems to exist.
