Add Simplified Chinese Documentation

[Yuerchu]

Hi!

I noticed that the documentation currently lacks support for Simplified Chinese (zh-CN). As a Simplified Chinese speaker, I would love to help translate the documentation into Simplified Chinese to make this project more accessible to users and contributors from China and other regions where Simplified Chinese is widely used.

I have already translated some content, such as:
NiceGUI 文本元素 NiceGUI Text Elements
NiceGUI ui.label

This is a translation of what was written on my personal blog. Since my blog is based on WordPress, it is not easy to preview the interactive components of NiceGUI.

I hope to upload my translated documentation to the repository in the form of a Pull Request, so that users can choose between Simplified Chinese or English on the official NiceGUI website.

How would that be done? Is it a complex change or could you create a pull request to show what you mean, @python-and-fiction ?

Not only chinese, any non-english document is needed for others.
So, we can add more pages of document which is translated into other language.
It looks like fastapi's website.
https://fastapi.tiangolo.com/
I can click language switch to visit chinese version website whose src is https://github.com/fastapi/fastapi/tree/master/docs/zh .
Some pages is still english, but someone wants to translate, they can create pr more easily.

We are not sure what's the best way to implement this. Just copying the website and letting people start creating pull requests feels not right. Ideally we we would have some translation lookup table which is used in the main documentation to pick the right language. Each table could then be auto-translated with an llm and then fine-tuned with pull requests without needing to touch the page content.

I think rodja is right. The best way is automatic translating.
Maybe chinese user can do this by using llm tools? @Yuerchu

I also recommend using llm, but I personally suggest that, if capable, allowing friends from the open source community to review it to find any potential translation errors. For example, certain proper nouns like "Quasar" might be force translated as "类星体" by translation programs, which is incorrect.
