Subject: [PATCH] Update part8e.md

a newer version of the `PubSub` class from `graphql-subscriptions` defines the method `PubSub.asyncIterableIterator` instead of `PubSub.asyncIterator`.

i've used the code in my codebase and it works!

for reference:
```config

        "@apollo/server": "^4.12.2",
        "@as-integrations/express5": "^1.1.0",
