Create zh_CN.lang

Some ore names of Metallurgy 4 is from https://github.com/TeamMetallurgy/Metallurgy4/blob/master/src/main/resources/assets/metallurgy/lang/zh_CN.lang.
I have checked it and found some mistakes, but for now I decide to use the current translations in case of mess.
Pls ignore the other PR for Chinese file, it seems that the translator know a little about the correct Chinese names of the items from TC4.
By the way, I have translated Ex-Nihilo and Ex-Astris to Chinese too.
