What is the current behavior?
the aws-appsync-auth-link and aws-appsync-subscription-link packages directly import graphql
https://github.com/awslabs/aws-mobile-appsync-sdk-js/blob/master/packages/aws-appsync-auth-link/src/auth-link.ts#L6

However package.json does not list graphql as a dependency, so it is not allowed to be imported when using a "strict" package manager like Yarn PnP

    Cannot find module 'graphql/language/printer' from '/Users/jvalore/Projects/ui/.yarn/__virtual__/aws-appsync-auth-link-virtual-6a00cc157f/0/cache/aws-appsync-auth-link-npm-3.0.7-6a8f1c0baa-0626782710.zip/node_modules/aws-appsync-auth-link/lib'

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.

try to use aws-appsync-auth-link in a modern Yarn PnP project and you will get the above error.

What is the expected behavior?

This package should list graphql in it's package.json dependencies since it is required.

Which versions and which environment (browser, react-native, nodejs) / OS are affected by this issue? Did this work in previous versions?
