🚸 script: ignore interfaces when inferring target

[cruzdanilo]

Motivation

currently, when running forge script without the --target-contract/--tc argument, forge will fail to identify the expected target contract if interfaces are declared in the same file, like in the following example:

// SPDX-License-Identifier: AGPL-3.0
pragma solidity ^0.8.22;

contract Script {
  function run() external {}
}

interface Interface {}

error:

Multiple contracts in the target path. Please specify the contract name with `--tc ContractName

Solution

the ux can be improved by ignoring artifacts with zero-length bytecode.
