Fix autoscaling_enabled broken

[nauxliu]

autoscaling_enabled is broken because bool will be converted to string value,

maybe is caused by the type constraints:

variable "worker_groups" {
  description = "A list of maps defining worker group configurations to be defined using AWS Launch Configurations. See workers_group_defaults for valid keys."
+  type        = list(map(string))

  default = [
    {
      "name" = "default"
    },
  ]
}
