Keep workflows active

Github will disable workflows for inactive projects, and a project goes inactive after 60 days with no commits.

This will stop smoke tests from detecting breaking changes from upstream package updates.

One solution (which I don't like, but I'm just leaving here to show there are automated solutions): https://github.com/marketplace/actions/keepalive-workflow

Alternatively, you have to pay attention to the github notifications and re-activate workflows each time you get an alert that they're being de-activated. From @DinoBektesevic:

Every 60 days or so without a commit, you just have to go to the actions tab and press "Enable worfklow" again. The issue I have with the automatic disable isn't that it happens it's that the notifications are by default enabled just for the person that made the workflow - not all "admins" or "maintainers" of the repo. This is how sometimes these things go by unnoticed unfortunately because people don't subscribe or watch the action (which I don't think you can do). There's an email GA that can be used as a replacement I believe.

Start by reviewing the repository's GitHub Actions workflows and the smoke tests that detect breaking changes from upstream package updates. Compare the automated keepalive approach with the documented manual reactivation process and notification behavior. Done should mean the chosen approach prevents the workflows from being silently disabled after periods without commits.
