Support `TypedDict` keys showing their docs on hover

[Gobot1234]

Description

from typing import TypedDict, Unpack

class Person(TypedDict):
    name: str
    """The name of the person."""
    age: int
    """The age of the person."""

def foo(**p: Unpack[Person]):
    print(p['age'])

foo(name="John", age=30)

Hovering over name would show "The name of the person." on the last line

[DetachHead]

it doesn't just happen with Unpack

Code sample in basedpyright playground

from typing import TypedDict

class Person(TypedDict):
    name: str
    """The name of the person."""
    age: int
    """The age of the person."""

person = Person(name="John", age=30)

person['age'] # no docstring on hover

looks like my example will be addressed in #1533

another thing: any plan of something like "go to definitions" working on literal key (subscript)?

[DetachHead]

could you provide an example? go to definition on TypedDict keys works for me now

@DetachHead oops sorry. I'm recently working on a project that uses pylance which does not have the capability. I just know basedpyright has already supported it.
