What this PR does / why we need it:

In openeuler/community, the English content is not updated. Thanks to @bluesky for raising this issue and started to work on:

!144:Add some content to use-guide file

Special notes for your reviewer:

  1. this PR synchronize the folders in ./zh and ./en.

  2. I translated most of the ./en, but still left some documents not translated and add one comment in the head of the files. I would like to get the folder structure and content agreed first.

  3. I think the following files are not valid or exist in other projects now, and I will submit another issue to confirm.

  • en/Gitee-Management
  • zh/Gitee-Management
  • en/sig-infrastructure
  • zh/sig-infrastructure

And you can skip these folders while reviewing.

  1. The folders en/contributors and zh/contributors are not detailed and please skip them while reviewing.
