Pinecone doesn't map to Pinecone-client

When installing the pinecone package (which pinecone-client maps to pinecone in the import statement), the installation fails as there's no valid distribution for the pinecone package. The package mapping should be updated to map pinecone->pinecone-client to avoid this guaranteed pip install error.

Locate the package mapping used by pipreqs and inspect how the imported package name is translated into a distribution name. Update the Pinecone mapping so pinecone resolves to pinecone-client, then verify that generated requirements can be installed with pip without the invalid pinecone distribution error.
