This is expected, you can't have 0 worker clusters today.
https://cloud.ibm.com/docs/containers?topic=containers-faqs#smallest_cluster

Note that you can't have a cluster with 0 worker nodes, and you can't power off or suspend billing for your worker nodes.

You can manually add a worker pool outside of terraform or remove one of the worker pools from the terraform state before running the destroy should you wish to import the default workerpool.

I acknowledge this is not ideal, but right now this is the best you can do
