Release v3.0.1

This is a quick follow-up to the v3.0.0 release earlier this week. This release adds improved error messages to help guide people on how to address some of the breaking changes in v3, such as the migration of core functionality from attributes on the pinecone module into methods of the Pinecone class.

If you're updating from v2.2.x from the first time, you will still want to checkout the v3.0.0 Migration Guide for a walkthrough of all the new features and changes. All of that information is still accurate for this release.
