Scale down and remove neurohackademy special nodepool

[GeorgianaElena]

Apparently we still had a node for neurohackademy still running. This should delete it.

Ref: #1620

Terraform plan output:

Terraform will perform the following actions:

  # google_container_node_pool.notebook["neurohackademy"] will be destroyed
  # (because key ["neurohackademy"] is not in for_each map)
