Thanks for adding a callout to the core python README.

The Assistant representation in the typescript client is fairly detailed if you're interested in modeling it around that: https://github.com/pinecone-io/pinecone-ts-client?tab=readme-ov-file#pinecone-assistant

Thanks Austin! Because we are currently have separated repos for the Python SDK and the plugin, this adds another place we need to keep in sync. I hope soon we will be able to merge the plugin and add documentation only here.
