[BUG] The endpoint '/shells/{aasIdentifier}/submodel-refs/{submodelIdentifier}' returns a code of 200 when successful.

[dk-emag]

Describe the bug
Calling the endpoint '/shells/{aasIdentifier}/submodel-refs/{submodelIdentifier}' successfully deletes a submodel reference, but the return code is 200 instead of 204 (as specified).

To Reproduce
Steps to reproduce the behavior:

1. Create a shell with at least one submodel reference
2. Delete submodel reference via endpoint '/shells/{aasIdentifier}/submodel-refs/{submodelIdentifier}'
3. Check if reference is deleted
4. Check return code is 200

Expected behavior
The return code should be 204 to indicate a successful deletion.

Thank you for reporting this bug. You are right. I will add it to our backlog. However, this won't be prioritized highly since it's not a critical bug.

Since it's an easy fix, I would recommend contributing the fix yourself.
