Fix/version order

#72 (comment)

The version sort by string. We may introduce the version.ParseSemantic from "k8s.io/apimachinery/pkg/util/version" to compare the version by semantic.

• coredns is not using v prefix. To use the version.ParseSemantic, we have to apply the prefix before comparing.

I am not sure if this is a best practice.

• kubeadm depends on coredns/corefile-migration
• coredns/corefile-migration depends on k8s.io/apimachinery v0.25.3

The import also seems to have a large impact in go.sum. Maybe we can just do our own implementation in line, e.g. ...

	sort.Slice(vStrs, func(i, j int) bool {
		iSegs := strings.Split(vStrs[i], ".")
		jSegs := strings.Split(vStrs[j], ".")
		for k, iSeg := range iSegs {
			if iSeg == jSegs[k] {
				continue
			}
			iInt, err := strconv.Atoi(iSeg)
			if err != nil {
				panic(err)
			}
			jInt, err := strconv.Atoi(jSegs[k])
			if err != nil {
				panic(err)
			}
			return iInt < jInt
		}
		return false
	})

or similar. It doesn't have to be bullet proof.

Updated.

The dep is not changed now.

@chrisohaver would you trigger a new release for #70?
