fix(core): remove devDependencies in production build

[mandarini]

Moved from https://github.com/nrwl/nx/pull/17744

All credits to @robdonn.

Current Behavior

When a local package.json is loaded with a devDependencies property, that property's contents end up in the final outputted package.json, even when isProduction is set to true.

Expected Behavior

When isProduction is true then devDependencies should be removed.

Why? Why is this not made optional (or at-least make this behavior opt in?), as a lib maintainer we add dev dependencies so that

1. the package is available when we are developing
2. we can import the package.json and copy it over if needed to the devDependencies of the users project
3. we can use a tool like ncu to easy update set packages that are added to the users project
4. we are then not forcing certain versions to our end users
