Accelerate prototyping and development with Pinecone Local

What this post added

Introduces Pinecone Local, a self-hosted, in-memory emulator of the Pinecone vector database. This feature enables local prototyping, testing, and development of AI applications, including integration into CI/CD pipelines. It supports all Pinecone SDKs and API endpoints without requiring an API key. The emulator is distributed via a Docker image (`pinecone-local`) and is designed for development and testing purposes, not production workloads.
