Some dependencies should be dev-only

[zarsky-broad]

When trying to run my react-scripts based app after upgrading this package to its latest version, I get a warning:

The react-scripts package provided by Create React App requires a dependency:

  "babel-loader": "8.0.5"

Looking at the changes, this commit appears to have moved a number of dependencies from dev to normal when upgrading them. Leaving this as-it would mean that any react-scripts app that uses a different version of that package would be unable to depend on this one.
