User Story
As a developer of the design system, I want all monorepo packages (no matter if released or not) to have the same version.

This would not only speed up the reviews of our release PRs, but also make it easier to debug.
It would simplify the version handling and therefore reduce compatibility issues and unexpected behavior.

Acceptance Criterias

• Add all monorepo packages (public/private) to the .changeset/config.json -> fixed array, so they are tied together from then on.
