zh-CN: Fix usage errors of some punctuations and translate some texts (…

…#1402)

I formatted the translation file on WSL. Worried about being failed
again, so I just improved some translations.

Update: Things seems very nice and I will continue my translating work.
Translation contributors who use Windows OS must use WSL instead of
using `dprint fmt` command on Windows itself, until the resolution that
can make the experience on Windows equal to Linux emerged.

To learn more about that, see this issue: #1394 .
