Transfer Chinese translation&change QQ group ID to plain text

The Chinese document homepage has been improved, so there is no longer a need to use English/Chinese as a proxy for navigation in English documents. The group ID is separated into a plain text after the link text to avoid various network issues, as it can be directly copied without accidental contact.

 As the project is international and English is currently studied the most commonly as a second language, it's the main project language. We do not limit the creation of language-specific community groups though, because we understand that many may not know English as well as their native language and/or may have trouble accessing Discord.
