Subject: [PATCH] Fix: incorrect type for Bdb.format_stack_entry (#13485)

```python
    def format_stack_entry(self, frame_lineno, lprefix=': '):
         ...
        frame, lineno = frame_lineno
```

The type of `frame_lineno` is `tuple[FrameType, int]` not `int`,
understandably, since the type of `frame_lineno` can be interprted as
the line number of the frame. But looking at the implementation of
`Bdb.format_stack_entry`, it is clear that `frame_lineno` is a tuple.

It is also necessary to somehow pass a frame to `format_stack_entry` if
we want it to be formatted...
