Remove clone command + add npx install

[carletex]

As we discussed yesterday, we are moving away from SE-2 clone method. The first step is to remove it from the docs / READMEs / etc.

Currently the below commands are hardhat specific

scaffold-eth-2/README.md

Line 46 in e5a666b

This command starts a local Ethereum network using Hardhat. The network runs on your local machine and can be used for testing and development. You can customize the network configuration in `hardhat.config.ts`.

Umm maybe make description for those 3 magic commands a bit more generic and then point to docs directly?

Sounds good, I can tweak them if you want

Sounds good.

Hardhat is also mentioned here

Maybe we should keep the README minimal and just link to the docs

[Pabl0cks]

Sounds good.

Tried to remove all the references to specific configuration of Hardhat, and pointed to the docs instead. Also pushed a couple of small tweaks:

• Add foundry to tech stack
• Add extensions hint in installation setup

Let me know if you prefer to remove any of that, or go more minimal in the Readme. Thanks! 🙌

Thanks! I think this looks great for first iteration!
