Release v6.0.1

This release contains a small fix to correct an incompatibility between the 6.0.0 pinecone release and pinecone-plugin-assistant. While working toward improving type coverage of the sdk, some attributes of the internal Configuraiton class were erroneously removed even though they are still needed by the plugin to load correctly.

The 6.0.0 pinecone SDK should now work with all versions of pinecone-plugin-assistant except for 1.1.1 which errors when used with 6.0.0.

Thanks @avi1mizrahi for contributing the fix.
