If a Shell is created via REST Request, a thumbnail can't be added to the AssetInformation.

To reproduce

1. Create Shell via REST Request (POST /shells):
   { "idShort": "123456", "id": "this-is-a-test-id", "assetInformation": { "assetKind": "Instance", "globalAssetId": "https://test-url.com/123456", "defaultThumbnail": { "path":"/aasx/thumbnails/this-is-a-test-id.png", "contentType":"image/png" } }, "modelType": "AssetAdministrationShell" }
2. PUT Image to thumbnail (PUT /shells/dGhpcy1pcy1hLXRlc3QtaWQ=/asset-information/thumbnail):
   multipart/form-data: file=image.png (image.png can be the png that you want to use as the thumbnail)

I managed to acquire additional knowledge. Adding an Image is only possible if an aasx file for this shell is present in the data-path folder. This can be "hacked" by manually downloading the package via the GET packages/{packageId} Endpoint.

However the problem seems to be bigger. Even if you add the thumbnail successfully it doesn't get written into the aasx file in the data-path folder. This results in all images (and persumably resources in general) to be lost after a reboot of the server. Should I open a dedicated ticket for this or do you want to handle it in this one?
