nivo: Error: Cannot find module '@nivo/core' after upgrading to 0.65.0

Describe/explain the bug After upgrading the Pie and Line charts to version 0.65.0 I’m getting the error Module not found: Can't resolve '@nivo/core'

To Reproduce In this codesandbox just bump the version of @nivo/pie to 0.65.0 to see the error https://codesandbox.io/s/nivo-core-required-zk09f?file=/src/App.js

Steps to reproduce the behavior:

1. Go here: https://codesandbox.io/s/nivo-core-required-zk09f?file=/src/App.js
2. Bump version to 0.65.0

Desktop (please complete the following information):

• OS: Mac Catalina
• Chrome

Additional context Maybe we just need to update the documentation if @nivo/core is required now
