* chore(nodejs): Use active LTS v20 for nodejs This updates nodejs to use the active LTS v20 from the maintenance LTS v18. This expands compatibility with packages, adds native support for more features, etc. In addition, the ci-seed-chain workflow was updated to use the .tool-version file instead of hardcoded version. * chore(hardhat): Update hardhat for nodejs 20 support |

Deploying contracts to test networks
A deploy script is included in this hardhat project to deploy a contract directly to a network. To deploy the contracts to different networks:

Configuration for various <network-name>s above are setup in the hardhat config.
Production compiling & Ethermint JSON
Ethermint uses its own json format that includes the ABI and bytecode in a single file. The bytecode should have no 0x prefix and should be under the property name bin. This structure is built from the compiled code with npm ethermint-json.
The following compiles the contract, builds the ethermint json and copies the file to the evmutil:
npm build
