Suggest updating the documentation to guide users to use system-installed fonts

Suggest updating the documentation to guide users to use system-installed fonts.

The documentation currently recommends using CJK fonts, but this support has been discontinued due to various issues.

We should update the docs to clarify that non-Latin scripts (e.g., CJK) should rely on system-native fonts, and users are encouraged to set their preferred fonts directly—for example:
```python
plt.style.use(["science", "no-latex"])
plt.rcParams["font.family"] = ["Times New Roman", "SimSun"]
```

Locate the documentation section that recommends CJK fonts and read its surrounding guidance. Update it to explain that non-Latin scripts should use system-installed fonts and include the provided font configuration example; done means the outdated recommendation is replaced and the example renders correctly in the documentation.
