Show using `snforge_std` and `sncast_std` from registry in docs

[cptartur]

In various places in documentation, we show using snforge_std and sncast_std from git. We should instead show how to use them from package registry.

I am applying to this issue via OnlyDust platform.

My background and how it can be leveraged

I am a web3 developer, I have expertise in smart contracts, decentralized technologies, and frameworks like React. I can build innovative dApps, contribute to open-source projects, educate others, and network with industry leaders to advance my career in the decentralized space. @cptartur Please can I be assigned to work on this?

How I plan on tackling this issue

I will Update the documentation to replace instances of using snforge_std and sncast_std from Git with instructions for using them from the package registry. Update code examples to reflect this new installation method.
