After the line Creation complete after - the worker nodes are still provisioning according to the UI (for at least a few minutes). In the scenario where the same apply create the new worker pool and scale the default worker pool to 0 worker nodes, this results in the following error

 Error: [ERROR] Error updating the worker_count 0: Request failed with status code: 400, ServerErrorResponse: {"incidentID":"06dfbf71-bf1a-4aa7-91d3-7b8e62b889ed,06dfbf71-bf1a-4aa7-91d3-7b8e62b889ed","code":"E1437","description":"The action cannot be completed because it would reduce the worker pool's size below the cluster's minimum requirement of 2 workers.

1. Perform a first apply with 2 workers in default
2. Add a second worker pool with at least 2 worker and update the default worker pool to 0 worker, run apply -> you'll see the error
