deploy.ts instead of deploy.json

[dk1a]

Inspired by #361 and the hardhat config

Currently deploy.json is a bit arcane in what it expects, and json is very strict with " everywhere.
Having a ts config with an attached type seems like it'd offer better devex and make deploy.ts easier to extend with more options without making those options super obscure.
Also a ts config partially solves the repeated writeAccess problem since you can use variables for similar arrays.

Naturally deploy.json and deploy.ts can coexist;
some other things to consider:

• mud uses ts anyways, deploy.js is not needed
• deprecating deploy.json might make sense, at least in the sense of not using it in tutorials, templates etc

basic hardhat.config.ts:

import { HardhatUserConfig } from "hardhat/config";
import "@nomicfoundation/hardhat-toolbox";

const config: HardhatUserConfig = {
  solidity: "0.8.17",
};

export default config;
