Doppler: Environment variable management

[Gizmotronn]

Problem:

1. Need to have .env variables ready and accessible by the entire team
2. Need to have the variables be easily accessible in .env files, and when cloning the repo so team members don't have to hunt through docs

Solution:

• Link VSCode repos on Git, Keybase, with Doppler (on producthunt.com) or similar alternative. Make use of the Doppler API
• Integrate that with the SK internal documentation
• Create scaffolding in the repositories (e.g. deddit inside Smart contract for "deddit" #7, marketplace-games inside this repo) for .env management
• Actually get the dotenv inside the repos to work
• Related to the above, inside marketplace-games/web3-test-game, the code below doesn't work:

require("@nomiclabs/hardhat-waffle");
import dotenv from "dotenv";
dotenv.config();

// This is a sample Hardhat task. To learn how to create your own go to
// https://hardhat.org/guides/create-task.html
task("accounts", "Prints the list of accounts", async (taskArgs, hre) => {
  const accounts = await hre.ethers.getSigners();

  for (const account of accounts) {
    console.log(account.address);
  }
});

// You need to export an object to set up your config
// Go to https://hardhat.org/config/ to learn more

/**
 * @type import('hardhat/config').HardhatUserConfig
 */
module.exports = {
  solidity: "0.8.0",
  networks: {
    rinkeby: {
      url: process.env.ALCHEMY_API_URL,
      accounts: [process.env.PRIVATE_KEY],
    },
  },
};
``` (`hardhat.config.js`)

Resulting in this output:
```bash
➜ npx hardhat run scripts/run.js
