Switch language name 'zh' to 'zh-cn'

This is the first step to rename 'zh' to 'zh-cn'. There are several reasons why we rename the language name. - The upstream docsy theme changed the language name, leading to many warnings during site build; The side-effect is that the i18n strings are no longer working. - We believe renaming the language is the right thing to do, because this move can make room for other variants of Chinese language, such as 'zh-tw', 'zh-sg' etc. There would be several follow-ups to this PR, such as fixing the intra-site links, adding redirects etc. We will lock up changes to zh/zh-cn pages for the moment, until this one gets in. This PR is based on commit cdad0a7342.

+## About CoreDNS
+
+[CoreDNS](https://coredns.io) is a flexible, extensible DNS server
+that can serve as the Kubernetes cluster DNS.
+Like Kubernetes, the CoreDNS project is hosted by the
+{{< glossary_tooltip text="CNCF" term_id="cncf" >}}.
+-->
+## 关于 CoreDNS
+
+[CoreDNS](https://coredns.io) 是一个灵活可扩展的 DNS 服务器，可以作为 Kubernetes 集群 DNS。
+与 Kubernetes 一样，CoreDNS 项目由 {{< glossary_tooltip text="CNCF" term_id="cncf" >}} 托管。
+
+<!--
+You can use CoreDNS instead of kube-dns in your cluster by replacing
+kube-dns in an existing deployment, or by using tools like kubeadm
+that will deploy and upgrade the cluster for you.
+-->
+通过替换现有集群部署中的 kube-dns，或者使用 kubeadm 等工具来为你部署和升级集群，
+可以在你的集群中使用 CoreDNS 而非 kube-dns，
+
+<!--
+## Installing CoreDNS
+
+For manual deployment or replacement of kube-dns, see the documentation at the
+[CoreDNS GitHub project.](https://github.com/coredns/deployment/tree/master/kubernetes)
+-->
+## 安装 CoreDNS
+
+有关手动部署或替换 kube-dns，请参阅
+[CoreDNS GitHub 项目](https://github.com/coredns/deployment/tree/master/kubernetes)。

+## Migrating to CoreDNS
+
+### Upgrading an existing cluster with kubeadm
+-->
+## 迁移到 CoreDNS
+
+### 使用 kubeadm 升级现有集群
+
+<!--
+In Kubernetes version 1.21, kubeadm removed its support for `kube-dns` as a DNS application.
+For `kubeadm` v{{< skew currentVersion >}}, the only supported cluster DNS application
+is CoreDNS.
+-->
+在 Kubernetes 1.21 版本中，kubeadm 移除了对将 `kube-dns` 作为 DNS 应用的支持。
+对于 `kubeadm` v{{< skew currentVersion >}}，所支持的唯一的集群 DNS 应用是 CoreDNS。
+
+<!--
+You can move to CoreDNS when you use `kubeadm` to upgrade a cluster that is
+using `kube-dns`. In this case, `kubeadm` generates the CoreDNS configuration
+("Corefile") based upon the `kube-dns` ConfigMap, preserving configurations for
+stub domains, and upstream name server.
+-->
+当你使用 `kubeadm` 升级使用 `kube-dns` 的集群时，你还可以执行到 CoreDNS 的迁移。
+在这种场景中，`kubeadm` 将基于 `kube-dns` ConfigMap 生成 CoreDNS 配置（"Corefile"），
+保存存根域和上游名称服务器的配置。
+
+<!--
+## Upgrading CoreDNS 
+
+You can check the version of CoreDNS that kubeadm installs for each version of
+Kubernetes in the page
+[CoreDNS version in Kubernetes](https://github.com/coredns/deployment/blob/master/kubernetes/CoreDNS-k8s_version.md).
+-->
+## 升级 CoreDNS 
+
+你可以在 [CoreDNS version in Kubernetes](https://github.com/coredns/deployment/blob/master/kubernetes/CoreDNS-k8s_version.md)
+页面查看 kubeadm 为不同版本 Kubernetes 所安装的 CoreDNS 版本。
+
+<!--
+CoreDNS can be upgraded manually in case you want to only upgrade CoreDNS
+or use your own custom image.
+There is a helpful [guideline and walkthrough](https://github.com/coredns/deployment/blob/master/kubernetes/Upgrading_CoreDNS.md)
+available to ensure a smooth upgrade.
+Make sure the existing CoreDNS configuration ("Corefile") is retained when
+upgrading your cluster.
+-->
+如果你只想升级 CoreDNS 或使用自己的定制镜像，也可以手动升级 CoreDNS。
+参看[指南和演练](https://github.com/coredns/deployment/blob/master/kubernetes/Upgrading_CoreDNS.md)
+文档了解如何平滑升级。
+在升级你的集群过程中，请确保现有 CoreDNS 的配置（"Corefile"）被保留下来。
+
+<!--
+If you are upgrading your cluster using the `kubeadm` tool, `kubeadm`
+can take care of retaining the existing CoreDNS configuration automatically.
+-->
+如果使用 `kubeadm` 工具来升级集群，则 `kubeadm` 可以自动处理保留现有 CoreDNS
+配置这一事项。
+
+<!--
+## Tuning CoreDNS
+
+When resource utilisation is a concern, it may be useful to tune
+the configuration of CoreDNS. For more details, check out the
+[documentation on scaling CoreDNS]((https://github.com/coredns/deployment/blob/master/kubernetes/Scaling_CoreDNS.md)).
+-->
+## CoreDNS 调优
+
+当资源利用方面有问题时，优化 CoreDNS 的配置可能是有用的。
+有关详细信息，请参阅有关[扩缩 CoreDNS 的文档](https://github.com/coredns/deployment/blob/master/kubernetes/Scaling_CoreDNS.md)。

+You can configure [CoreDNS](https://coredns.io) to support many more use cases than

+for the `kubernetes` CoreDNS plugin, or read the 
+[Custom DNS Entries for Kubernetes](https://coredns.io/2017/05/08/custom-dns-entries-for-kubernetes/)

+你可以通过修改 CoreDNS 的配置（"Corefile"）来配置 [CoreDNS](https://coredns.io)，
+以支持比 kube-dns 更多的用例。
