…GET_SOLC_BUILD subtask

What 💻

• Make compilationJobs argument optional at TASK_COMPILE_SOLIDITY_GET_SOLC_BUILD subtask

Why ✋

• Some users do not use the extended Hardhat subtask, so we will make this additional argument optional. This way, the compilation process will not default to using the forked Era Solidity compiler. When used in this manner, there may be differences in bytecode because, with the argument enabled, the forked Solidity compiler is used; otherwise, the native compiler will be utilized.
