chore(docs): include `raw-components` and `health` stories in the local build

[schaertim]

📄 Description

Some of the stories should only be shown when the docs are run locally. Up to now, they were just hidden from the navigation sidebar using css. That meant they could still be found and accessed by searching for them in the searchbar. As a more robust solution instead of just hiding them with css i added logic to not include them in the build at all if we are not in the dev environment.

🚀 Demo

If applicable, please add a screenshot or video to illustrate the changes.
