ObjectStoreDatasetManager.create does not add content_type to metadata file

[aaraney]

The ObjectStoreDatasetManager's create method does not add the "application/json" content-type to a serialized Dataset during upload. Consequently, you cannot preview a serialized Dataset in the minio UI.

DMOD/python/lib/modeldata/dmod/modeldata/data/object_store_manager.py

Line 517 in 4677879

result = self._client.put_object(bucket_name=name, object_name=self._gen_dataset_serial_obj_name(name),

This is a super easy fix, the content_type should be added as shown:

        result = self._client.put_object(
            bucket_name=name,
            object_name=self._gen_dataset_serial_obj_name(name),
            data=io.BytesIO(bin_json_str),
            length=len(bin_json_str),
            content_type="application/json"
        )
