Merge pull request #126 from threshold-network/upgrade-hardhat-deploy

Upgrade `hardhat-deploy` to latest version (`^0.11.15`)

We want to upgrade `hardhat-deploy` dependency to latest version. Previously used version is not working correctly with a `@nomiclabs/hardhat-etherscan` plugin which we plan to use in the near future.
Apart from updating `package.lock` and `yarn.lock`, we had to change how we store the Etherscan key in Hardhat config file, because the syntax for that got changed in the newer versions of `hardhat-deploy`.
