[Bug] index.list() error message for non-serverless indexes is unclear

What was reported

Issue pinecone-io/python-sdk#331 (closed, 8 comments): ### Is this a new bug in the Pinecone Python client?

• [X] I believe this is a new bug in the Pinecone Python Client
• [X] I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

I followed the code exactly from the documentation

from pinecone import Pinecone

pc = Pinecone(api_key value [redacted]
index = pc.Index('self-retriever-pae')

# To iterate over all result pages using a generator function
for ids in index.list( namespace="Non_Varicea"):
    print(ids)

This succeeds (as expected) against a serverles

The verified resolution

[cbelsole (reporter), acknowledged by daverigby (maintainer)]: index.list() only works on serverless indexes - calling it on a pod-based index fails with a confusing error. Maintainer re-opened the issue to make the error message explicit for non-serverless indexes. Rule of thumb: use list()/list_paginated only against serverless indexes.
