Doc translation tasks

**Task description**:

Kmesh maintains doc in Chinese and English.

However Kmesh is in the rapid develoment process, so some docs may only be in Chinese or English.

It would be appreciated if you could help translate the doc. 😃 😃 😃

**Solution**:

The docs are mainly in the [docs](https://github.com/kmesh-net/kmesh/tree/main/docs) and [docs/proposal](https://github.com/kmesh-net/kmesh/tree/main/docs/proposal) subdirectories, as well as the [README file](https://github.com/kmesh-net/kmesh/blob/main/build/docker/README.md) that may be in some subdirectories.

Pick the one you like and start right away. 🚀 🚀 🚀
