Make ts-node as optional package

Is your feature request related to a problem? Please describe. ts-node only needed if configuration is written in Typescript. ts-node is ugly implementation of TS loader, so most of users go to TSX or manually compile config before

Describe the solution you'd like Describe ts-node as optional peer dependency ("peerDependencies" + "peerDependenciesMeta")

The only one demand of ts-node in my node_modules is that it's dependency of builders/custom-webpack
