Strict typing on dependencies

[JanssenBrm]

The typing on the dependencies key is too strict, not allowing it to include additional fields. The strict convention is not necessary as the field is also mapped as flattened in ElasticSearch, so there is no need to search for its detailed properties. Additionally, the strict validation requires an update of the code every time a new field is added.

Referring to Open-EO/openeo-geopyspark-driver#786, this is the original ticket where this behaviour was detected.

Ok, I was under the impression that this was an issue with the mapping but it's in the application instead.

Thanks for the quick fix.

Indeed I noticed that the application was still applying some typing and validation to the dependencies object so I removed the specific typings. I also checked the other fields and they now all either have a basic type (string, number or boolean) or a generic any type
