Typst: Show File Names of Code Blocks

[MathisC22]

Description

File names of code cell blocks are not shown when using Typst as backend, whereas they do show when you use LaTeX or HTML to render the file. That is, the following cell only shows the contents:

```{.python filename="matplotlib.py"}
import matplotlib.pyplot as plt
plt.plot([1,23,2,4])
plt.show()
```

Would be really neat if it would also work with Typst!

This is indeed not supported. We need to add support for it. Thanks !
