Use babel-node instead of ts-node when running benchmark script

Summary:
`ts-node` does transformation using tsc. Do transformation with Babel instead so that the generation is consistent with Jest and the packed output.

We still need `ts-node` around since various systems rely on it being present to enable `.ts` config files.

This also enables transformation of any JS files.
