Looks good! Can you add the two changelog entries as well please?

@Fyusel I am not sure what is generated and what not and where to add it in the change log. Should I add an entry in the model-serving folder like

## v0.2.0 (2025-03-10)

- **New**: STACKIT Model Serving module wait handler added.

## v0.1.0 (2025-02-25)

- **New**: STACKIT Model Serving module can be used to manage the STACKIT Model Serving.

And potentially also in the root Changelog like:

## Release (2025-03-10)
- `model-serving`: [v0.2.0](services/modelserving/CHANGELOG.md#v020-2025-03-10)

## Release (2025-03-05)

- `core`: [v0.16.1](core/CHANGELOG.md#v0161-2025-02-25)
  - **Bugfix:** STACKIT_PRIVATE_KEY and STACKIT_SERVICE_ACCOUNT_KEY can be set via environment variable or via credentials file.

???

Yes, that is correct except that in the root changelog the release date is 2025-XX-XX and also the one line should be added there "New: STACKIT Model Serving module wait handler added.".
