Add Translation

[VLTHellolin]

Hi,

These days I'm working on a Simplified Chinese translation of the ACL documentation, and I would like to ask if you'd be willing to add the translation to this official doc repo.

If you're not good at Chinese, I will help maintain the translations so you don't have to worry about it.

For more info, see OI-wiki/OI-wiki#5515, it contains the translation files.

Thanks.
