[spruce] Bump @pinecone-database version to support global control plane

[austin-denoble]

Problem

We've been working to support the new global control plane service in the Pinecone clients. We need to update our sample apps to migrate to the new client versions, and update associated code paths as needed.

Solution

• Bump the @pinecone-database/pinecone dependency to use the new spruceDev version of the client: ^1.1.2-spruceDev.20231214000822.
• Update pinecone.ts and seed.ts to handle the new object response from listIndexes().
• Update seed.ts to pass the proper config object shape to createIndex().

For now, I've created a spruce branch to merge this into as we probably don't want to release sample apps that aren't aligned with what's available publicly.
