weird baseline issue in multilanguage LaTeX objects

Nobody has claimed this yet.

## Description of bug / unexpected behavior
When mixing Chinese script and Western text inside the same `Tex()` object using the `TexTemplateLibrary.ctex` or XeLaTeX directly, the baselines of the Chinese script is not adjusted to the rest of the text. Running the same code on Docker with Manim v0.16.0 results in a correct rendering.

## Expected behavior
The baseline generated by LaTeX/XeLaTeX should be preserved.

## How to reproduce the issue

Code for reproducing the problem

```py
class MyScene2(Scene):
def construct(self):
tex = Tex(r'Hallo 你好 \LaTeX', tex_template=TexTemplateLibrary.ctex).scale_to_fit_width(12)
self.add(tex)
self.wait()
```

## System specifications

System Details

- OS: Windows 10
- Python version 3.9.8
- XeTeX, Version 3.141592653-2.6-0.999995 (MiKTeX 23.5)

## Additional comments

same unwanted behavior is observed on the Manimator on Discord

Reproduce the issue with the provided MyScene2 example using TexTemplateLibrary.ctex and XeLaTeX on the reported environment, then inspect the Tex rendering and template path. Compare the mixed Chinese and Western text output with the Docker and older Manim results; done means the generated baseline matches the expected LaTeX/XeLaTeX alignment.
