[Bug]: Angular enableProdMode gets ignored

[kroeder]

Describe the bug

I noticed Angular didn't print a couple of expected errors on console and I also haven't seen the typical "Angular is running in development mode." (or something similar)

A quick research showed, that you can properly set enableProdMode, it also is correctly read from the builder config but it is ignored later on after all.

Workaround: set NODE_ENV=development before running Storybook.

Reproduction steps

1. Start storybook
2. See missing "Angular is running in development mode." in console.
