data files are missing in sample notebook for multi-model-milvus search in Tutorial

We are trying to test out the multi-model milvus search [sample](https://github.com/IBM/watsonx-data/blob/ed661bc76e3063e2f9f6cc4835df36f8b4ddd515/Tutorials/multi-modal-search.ipynb#L885) but found none of the sample data files (e.g. /data/preprocessed_df.pkl')  is in github. Is there any way to upload the sample data file so we could run through the sample notebook?
