Autocompletion when constructing anonymous `TypedDict` in function calls

### Describe the Bug

I'd like autocompletion when constructing anonymous dictionaries in function calls that expect a `TypedDict` as the argument.

For example:

```
from typing import TypedDict

class Box(TypedDict):
x: float
y: float
z: float

def take(box: Box):
return

take({""})
# ^ When the cursor is in this position, there's no autocompletion of the keys in `Box`
```

Pyright *does* have this behavior. I think it would be very beneficial to add this to `Pyrefly`.
