Clean zh/docs directory for dangling YAML files (#17341)
There are many YAML manifests sneaking into the `zh/docs/` directory. These files should go to the `zh/examples` directory instead. Having these "garbage" files (not referenced anywhere) is creating confusion for the release meister when merging branches. For example, some YAML files found in the 'master' branch are no longer there in the release-1.16 branch. It is tedious, if possible at all, to solve all this kind of conflicts during a rebase. The PR cleanses the zh/docs directory for all dangling YAML files.

gcloud compute disks create --size=20GB mysql-disk

```
