Update jina embedding notebook to show multimodal capability more clearly (#23702)

After merging the [PR #22594 to include Jina AI multimodal capabilities
in the Langchain
documentation](https://github.com/langchain-ai/langchain/pull/22594), we
updated the notebook to showcase the difference between text and
multimodal capabilities more clearly.
