Mixed types with values in docs

The types are mixed with values in this docs
https://pothos-graphql.dev/docs/plugins/smart-subscriptions
```ts
const builder = new SchemaBuilder({
plugins: [SmartSubscriptionsPlugin],
smartSubscriptions: {
debounceDelay: number | null;
subscribe: (
name: string,
context: Context,
cb: (err: unknown, data?: unknown) => void,
) => Promise | void;
unsubscribe: (name: string, context: Context) => Promise | void;
},
});
```

btw. I'm struggling with working example with yoga graphQL. It will be nice to have working example and more documentation.

TY & GJ, I love this lib ❤️

Open the smart subscriptions documentation page and review the TypeScript configuration snippet shown in the issue. Correct the mixed type/value notation and, if the Yoga GraphQL example is in scope, document a working example. Done means the snippet is valid and the page explains a working Yoga integration clearly.
