docs/zh_CN: polish how-to.rst

Editorial pass on the Chinese translation contributor guide.

 - Fix typos: 网络通常 → 通畅; remove trailing backticks on the
   checktransupdate.py command; mis-placed 。 → , in the 紧急处理
   section; 您/你 and 的/地 inconsistencies in 进阶.
 - Correct "git email" to "git send-email", matching usage
   elsewhere in the document.
 - Replace an invalid <URL> inline form with a bare URL so Sphinx
   renders the lore.kernel.org link.
 - Tighten grammar and wording: 针对于 → 面向; drop redundant
   最多 before 不超过 and tautological 即可; remove double 的 in
   您的翻译的内容; resolve ambiguity around 继续 placement in the
   把补丁提交到邮件列表 section; and similar small fixes.
