Broken colors in forked processes

[dkundel]

It seems like chalk turns supportsColors to false in forked processes for some reason. We can turn that back on by adding FORCE_COLORS as 1. There's an example in this issue for chalk chalk/chalk#381.

The only thing for us to consider is that we'll override that process.env after spawning the forked process with the actual environment.

Alternatively, we could try passing the original stdin, stdout and stderr from the parent process. It looks like you can do that with the stdio option for fork.

    const forked = fork(RUNNER_PATH, { stdio: 'inherit' });

Nope, that does not work. FORCE_COLORS seems to be the way.
