fix: configuration of kube-vip per-service leader election

Previously used `enableServicesElection` is not an accepted environment
variable but a field in the kube-vip YAML config file.

* The related environment variable is `svc_election`, which is already
  present in the DaemonSet template
* Use `rke2_kubevip_service_election_enable` to set the `svc_election`
  in DaemonSet template
* Change default value to `true` to maintain original behavior
