image_description should be product_description

[JiahongXieEthan]

In multimodal_search_with_opensearch_service.ipynb the payload for open search ingest pipline is:

payload = {
"description": "A text/image embedding pipeline",
"processors": [
{
"text_image_embedding": {
"model_id":model_id,
"embedding": "vector_embedding",
"field_map": {
"text": "image_description",
"image": "image_binary"
}}}]}

But there was never a image_description, do you mean product_description?
