read-package-json raises an error when the package name is not valid

Some libraries such as `@apollo/client/react` has no an standard package name so when webpack tries to compile raises an error like this, due [read-package-json](https://github.com/npm/read-package-json) validation.

```textplain

```

I suggest to change the way package.json is loaded using the default require method which is `nodejs` standard, it will validate only the format and not follow the `npm` structure.
