Update callbacks.md

This update fixes an issue with @types/next-auth. Since the Session type doesn't have an accessToken value you need to set it in the return statement. Since the return is WithAdditionalParams we can tack on accessToken there.

Thanks for raising a PR 💚

I think the examples on the websites are currently just in plain JS, hence I don't think we should be using TS syntax on them.

There's an epic going on to move the types to this repo to make them easier to maintain. When we ship the new types 🚀 ( hopefully around end of next week ) they'll come with support for module agumentation which I think will help in this specific issue.
