feat: enable Hardhat interval mining mode

- This change enables interval-mining mode on Hardhat network. Without this, tx.wait(2) doesn't work(block waiting forever), as Hardhat won't mine new blocks when no new transactions sending. Ref: https://hardhat.org/hardhat-network/docs/explanation/mining-modes
