Deployed contracts on testnet and mainnet

- Deployed all v1 contracts on Rootstock Testnet and `BalanceHelper` and `BalanceHelperV2` on Rootstock Mainnet.
- Added chain configs for Rootstock Mainnet.
- Added `balanceHelpers` tag on deployment script to make it easier to solely deploy balance helper contracts.
-Upgraded hardhat-etherscan package to later version.
