Addition of ?assetIds query parameter to the GET /shell-descriptors endpoint

[aaronzi]

What is missing?

Currently, only the GET /shells endpoint for getting all shells from the AAS Repository supports filtering based on given assetIds (see screenshot below).

It would be nice to have the same query parameter in the AAS Registry as well. The necessary data for implementing this is already present in the descriptor (see screenshot below).

How should it be fixed?

The API endpoint getAllShells should be extended by the assetIds param so that it is possible to get all shells with a given assetId.
