Describe the feature

Hi! I'm currently writing an integration of Pinecone for an agentic AI framework called Rig which you can find more about here: https://github.com/0xPlaygrounds/rig

I noticed that ListValue doesn't actually get re-exported from prost_types so I ended up having to add the prost-types crate to add it. It would be great if pinecone-sdk re-exported it so I am not forced to add another dependency just for one type.

Describe alternatives you've considered

There aren't exactly any alternatives besides just not doing anything

Who will this benefit?

Literally everyone
