[Improve][Doc] Change the README.md file

[hnrainll]

Description

1. When I first initialized the project as described in README.md, I found that the node version already needed to be upgraded to v16.14.0
2. Add instructions for browsing zh-CN documents

This is what confused me the first time I ran the project.
