Docs Issue: middleware Typescript errors

Docs listed here produce typescript errors - https://chanfana.pages.dev/advanced-topics-patterns#middleware-and-interceptors

```
No overload matches this call.
The last overload gave the following error.
Argument of type 'typeof ProtectedEndpoint' is not assignable to parameter of type 'H<{ Bindings: Env; }, "/protected", BlankInput, Promise>'.ts(2769)
types.d.ts(774, 5): The last overload is declared here.
```

Any ideas?

Open the middleware and interceptors section at the linked documentation page and reproduce the reported TypeScript error. Trace the example and its type-checking context; done means the documented middleware example no longer produces the reported overload error.
