Release v4.0.0

3x boost to upsert throughput via grpc

In this release, we are upgrading theprotobuf dependency in our optional grpc extras from 3.20.3 to 4.25.3.

This is a breaking change for users of the optional GRPC addon (installed with pinecone-client[grpc]). Detailed performance profiling by @daverigby showed this dependency upgrade unlocked a 3x improvement to vector upsert performance in the Python SDK, bringing it much closer to the performance observed in our grpc-based Java SDK.

As a reminder, to use use the optional grpc extras for improved performance, you need to install pinecone-client[grpc] and make a small modification to how you import and use the client. See the instructions for doing this here.
