[Docs] Update tuple output examples in flytesnacks/flytekit docs

[cosmicBboy]

Description

currently our docs have output function sigs for tuples as

def func() -> (int, str):

We added support for the correct syntax:

def func() -> Tuple[int,str]:

The purpose of this issue is to update all instances of the former to the latter

@cosmicBboy Can I take this one?

[cosmicBboy]

@Qiwen-Yu yes! let me assign you. Also let me know if you need any help setting your repo up. Examples in both flytekit and flytesnacks probably need to be updated.

[Qiwen-Yu]

Correct me if I were wrong, the scope is to fix all tuple type hints to Tuple[] for files in https://github.com/flyteorg/flyte/tree/master/rsts, https://github.com/flyteorg/flytekit/tree/master/docs and https://github.com/flyteorg/flytesnacks/tree/master/cookbook, am I right?

[cosmicBboy]

yep, that's correct!
