code in figures are centered in docx documents

Bug description

When a .qmd document is rendered in docx, then each line of the python code in the figure will be centered, which makes it completely unusable.

the bug doesn't appear with the .odt, .tex or .html format

The code-line-numbers functionality also doesn't work. But nothing in the documentation states that it should work for formats other than tex and html, so maybe that's normal.

PS: (Any chance .odt will work with the book format at some point ?)

Steps to reproduce

---
format: docx
---

::: {#fig-python} 

```{.python code-line-numbers="true"}
for i in range(3):
    print(i)
    if i < 2:
        print(i+1)
```

interesting code 
:::



```python
for i in range(3):
    print(i)
    if i < 2:
        print(i+1)
```

Expected behavior

The figure should be left aligned, and the spacing from python should be respected

Actual behavior

Each row of the code in the figure is centered

(bug also happens on 1.7.13)

Start by rendering the supplied .qmd example with Quarto 1.6.40 or 1.7.13 and compare its docx output with the odt, tex, and html outputs. Trace the docx rendering path for code inside figures; done means the figure code is left aligned, Python indentation is preserved, and the expected status of code-line-numbers is documented or verified.
