`cockpit-lib-update` fails by default

[Venefilyn]

Currently there is no docs within the starter-kit on how to update the workflows or what workflows exist and what they all do

With the cockpit-lib-update it is scheduled to run regularly but does not actually work on repos by default from this template. We instead get an error in the Run cockpit-lib-update step with:

Run make bots
git archive '52222a2d3198fd05bbbbb75e35bc0970c2b4ae77^{tree}' -- pkg/lib test/common  | tar x

Sure, this needs a key setup for you to push to a GitHub repository. We automated this away with setup-deploy-keys, the best we can do is leave some instructions there.
