Update Simplified Chinese Translation

[yhdsl]

I have made a complete update of the Chinese Translation, in summary, i have completed the translation and proofreading of all the translation, the complete fix text will be attached later.

I've read the translation guide on this site, as well as read this #4657 notes on Chinese Translation, and verified it inside a self-deployed Docker container.

The complete revision includes:

• Ensure that all entries are covered (previously untranslated entries and translations that have become obsolete due to text changes)
• Unified translation style (I made some adjustments for Chinese pages and reading habits)
• Adjusted the grammar of some translations, such as placing the verb first instead of last
• Go through all the translations and fix multiple typos and incorrectly used HTML tags (that are no longer used in the English entry) in conjunction with the UI
• Adjust the order of the entries to make sure they match the English entries (I think this will look easier :D)

I hope this will be helpful

May I ask why you closed this PR @yhdsl?

[yhdsl]

I got confused about the meaning of the button, due to I am not familiar with the operation of github

I hope I didn't screw anything up @MAGICCC
