Depend upon traitlets >5.13.0 (#14353)

In previous versions, `traitlets.List` does not inherit from
`typing.Generic` which means it does not implement `__class_getitem__`
which means
[`List[ast.NodeTransformer]`](https://github.com/ipython/ipython/blob/8.22.0/IPython/core/interactiveshell.py#L331)
raises at runtime.
