Eject adds build tools to `dependencies` instead of `devDependencies`

[jackHedaya]

Describe the bug

When running react-scripts eject, the generated package.json has loaders, webpack, jest, etc all in dependencies. Correct me if I'm wrong, but these fields should all be in devDependencies instead.

Did you try recovering your dependencies?
