Grab workload version in K8s tutorial #2282
Description
As follow-up work to #1749, I recommend that we make use of the workload module that comes with the Charmcraft profile. I think it would be great to modify the workload module to fetch the version from the API server, then the charm can set the workload version accordingly.
I don't think this would need to be a separate chapter - we should be able to add it to Create a minimal Kubernetes charm.
