Chinese translation of title template, headings, labels

[cicirello]

Summary
Add Chinese translations of title template, headings, labels, etc for locale code zh.

Potential Contributors
See Contributing a Translation section of the README for step-by-step instructions.

Please don't edit the README with the new locale code, despite the Pull Request template requesting that documentation is updated. Changes to the README automatically go live in the GitHub Marketplace listing for the action. I'll take care of updating README with the new locale code in the list of locales when I create the release that contains it to ensure that documentation is consistent with latest release.

@cicirello can i be assigned to this?

[cicirello]

@Jibendu007 Yes. Do you happen to know if zh is the correct code for this? It appears to be the only one I can find for Chinese, but not clear if it is meant to be for Mandarin or not.

[Jibendu007]

According to what I have read from the "Internet" IT SEEMS TO BE zh. Will look into it more while working.

Yup, for mandarin, we can use zh as the language code.

For Multiple Chinese language, I think we usually use the country code also, because mostly depend on the country itself. Like this article:

I also found the answer about that:

@berviantoleo Thanks. That explanation for the language code is helpful.
