Update hooks `args` and `return` values more readable

[technophile-04]

Description :

Regarding useScaffoldContractRead & useScaffoldContractWrite

I think it would be really great if we link to wagmi's useContractRead return value and others args which our hooks take in and it will people know their types. Similar for useScaffoldContractWrite

Regarding useScaffoldEventHistory & useScaffoldEventSubscriber :

useScaffoldEventSubscriber is similar to wagmi's useEventSubscriber so we can add a small link to wagmi.

useScaffoldEventHistory :

Maybe we describe return values in pointer so that its more easily recognized and readable ?

I'll work on a proposal tonight with those improvements 🙌
