Description of the bug

Here is the markdown:

```python
def __exit__(self, exc_type, exc_value, traceback) -> None:
    """
    Automatic breakpoint removal.
    """
    self.remove()
```

```python
__exit__(exc_type, exc_value, traceback) -> None
```

::: pwndbg.dbg.StopPoint.__exit__

It renders like this:

The exc_type parameter shouldn't be highlighted. It is wrongly marked as nf by pygments which is for functions.

To Reproduce

git clone https://github.com/k4lizen/pwndbg
cd pwndbg
git checkout weird-high
uv run --group docs mkdocs serve --strict

Look at http://127.0.0.1:8000/pwndbg/setup/

Expected behavior

The exc_type parameter shouldn't be highlighted. It is wrongly marked as nf by pygments which is for functions.
