KAL incorrectly recommends making a *[]corev1.Taint field with MinItems=0 a non-pointer

[sbueringer]

We found this while using KAL in Cluster API, xref: kubernetes-sigs/cluster-api#12299 (comment)

The field looks like this

	// +optional
	// +kubebuilder:validation:MinItems=0
	// +kubebuilder:validation:MaxItems=100
	Taints *[]corev1.Taint `json:"taints,omitempty"`

And we get this finding

api/bootstrap/kubeadm/v1beta2/kubeadm_types.go:304:2: optionalfields: field Taints is optional but the underlying type does not need to be a pointer. The pointer should be removed. (kubeapilinter)
        Taints *[]corev1.Taint `json:"taints,omitempty"`
