Support Simplified Chinese Translation

[aimerneige]

As in title.

Jsut a little work. I did not do build test.

if you tested it in the test environment then it is safe to merge; if the translation is untested I won't merge it

[aimerneige]

Got it. I will do the test.

[aimerneige]

I build a deb package and install it on a clean installed ubuntu 22.04 kvm virtual machine. It works fine.

[NyaomiDEV]

there is a test that was not conducted; does sunamu use simplified chinese in a machine or vm which is configured to use simplified chinese? I mean without uncommenting the language in the config file

[aimerneige]

I recoverd vm's snapshot and set the languge to Chinese. Then I install Sunamu, without touching the config file. It display English.

[aimerneige]

When I try to comment the language config, sunamu just write a newline into it.

    language: "en",

This is not supposed to happen. Can you do language: "" for now?
