Add Readme.md for Chinese.

I've added a full Chinese version!

I kinda felt uneasy about translating official docs, mostly because I wanted them to be maintained only by actual project maintainers and kept up-to-date. And given how fast WebCord does really change, it's easy for the docs to be actually outdated; I think even Polish official docs are out of sync right now with the English version and for those I've only translated.

I guess might reconsider this a bit. Maybe I'll do simple checks before merging it (in case of docs), like with Google Translate or sth...

Also, for some reason, I have a feeling that projects in general with Chinese docs are perceived like they are allowed for conversation to be made in Chinese (possibly due to my interest in Android modding community, which tends to be flooded with the maintainers from Asian countries) . I'm kinda uneasy with that fact (I don't really know Chinese, I guess that should be obvious by looking at the commits / repo at the current state); please add a disclaimer (if you didn't; I hardly checked the translation for now) that those docs are maintained by the community, they might be outdated and that you should prefer communicating in English with the maintainers (me).

Don't worry, I'll gradually keep following up on the translation.

And I will add a disclaimer!

The overall translation looks fine and passes Google translate test well. I would still modify some things and I'd love to have some things explained before I'll pull this.

You probably want to create a copy of the HTML table, and go with something like alert-info as a class value to style it properly. This is kinda non-MD / custom styling I use in WebCord docs, yet I might go with GH markdown alerts in the future, since those were recently announced and seem to be somewhat stabilized + marked already supports it / has an extension to introduce support for it.

Better English and emoji? (See Polish docs for template on it)

I would update this whole section, making it somewhat a combo of flag / language name (or just flag), just so it would be more fitting for multiple languages without taking a lot of the space.

Could you confirm that Chinese plural rules are the same like in English? Do you have any other rules in some cases, like for little number of things vs large amount (this happens in some languages for instance in Polish there's few and many rules, few are for numbers/digits like 2,3,4 and many describes form for basically other set of numbers/digits)? If you're unsure on that, you might as well verify it in the practice; WebCord will automatically use the rules from this config for the number that is placed before the translation.
