zh_cn: update and revise translation

This absorbs the good parts of TehNut-Mods#156 and its review comments. Changes include:
* Proper chinese punctuation (`：` instead of `: `)。
* Use the colloquial on/off (开/关) instead of the circuit close/open (闭/开), consistent with en and this thing being a game.
* Correct mistake where comparator is called an adder (seriously?)
* Use proper translation for sneak (潜行) instead of "crouch" (下蹲)
* Add separate entry for nitwit in anticipation of TehNut-Mods#220 fix.

Close TehNut-Mods#156.
