feat: integration openzeppelin evm template

[AlexD10S]

PR to support OZ EVM template: https://github.com/OpenZeppelin/polkadot-runtime-templates/tree/main/evm-template

To support EVM chains in Zombienet, the config file includes force_decorator = "generic-evm". When this field is present, pop injects evm_based = true to ensure compatibility with Zombienet-SDK after the recent fix: paritytech/zombienet-sdk#256
