Show `typing.Annotated` info in tooltips

I work with PyTorch and want to be able to annotate tensor types with shapes.

I tried `jaxtyping` module like this:
```python
def foo(x: jaxtyping.Float[torch.Tensor, "B T E") -> jaxtyping.Float[torch.Tensor, "B T 1"]: ...
```

Unfortunately, in VS Code when I hover over `foo` callsite or the definition, VS Code loses extra annotations:

```python
def foo(x: Tensor) -> Tensor: ...
```
