*Show cell source with optional line numbers*

[`view_cell`](https://AnswerDotAI.github.io/pyskills/ipynb.html#view_cell)
displays a cell’s source with line numbers, useful for checking content
before editing:

``` python
print(view_cell(_nb_path, _cid))
```

         1 │ two
         2 │ three
         3 │ GAMMA
