Fix GraphQL Hooks Example Safari bug (#14205)

Fixes #14187, where the [GraphQL Hooks Example](https://github.com/vercel/next.js/tree/canary/examples/with-graphql-hooks), when opened in Safari, doesn't respond to events in production and doesn't load at all in the dev server.

This is caused by [a bug in graphql-hooks-memcache@1.3.2](https://github.com/nearform/graphql-hooks/issues/496), which they've fixed but haven't released the fix yet. So this example fix just temporarily downgrades graphql-hooks-memcache by changing its version range to `1.3.1 || ^1.3.3`.
