Why AWSManagedMachinePool's TaintEffect is different from Node's TaintEffect?

[davidwtf]

In CAPA, we use TaintEffect "no-schedule", "no-execute" and "prefer-no-schedule".
(The definition is here: https://github.com/kubernetes-sigs/cluster-api-provider-aws/blob/v2.2.1/exp/api/v1beta2/types.go#L211)

But the Kubernetes node uses TaintEffect "NoSchedule", "NoExecute" and "PreferNoSchedule".
(Refer to: https://github.com/kubernetes/kubernetes/blob/v1.27.4/staging/src/k8s.io/api/core/v1/types.go#L3135)

I think they are talking about the same thing.
But why do we use different values?
Now I have to process the conversion between them.
