Code line numbers for Docusaurus

[eitsupi]

Quarto supports the display of line numbers in code blocks in HTLM format, etc.
https://quarto.org/docs/output-formats/html-code.html

The syntax is thus.

```{.python code-line-numbers="true"}
import matplotlib.pyplot as plt
plt.plot([1,23,2,4])
plt.show()
```

The syntax in Docusaurus seems to be as follows, showLineNumbers is needed.
https://docusaurus.io/docs/markdown-features/code-blocks#line-numbering

```python showLineNumbers
import matplotlib.pyplot as plt
plt.plot([1,23,2,4])
plt.show()
```

It would be great if Quarto could support this conversion.

Yes I think this should be supported. I transformed to issue #5152 to track this ! Thanks
