🚀 Feature: For functions, provide the type.

### 🔖 Feature description

This issue is the same as
[Appwrite #8329 Issue](https://github.com/appwrite/appwrite/issues/8329)

Simply put, this involves adding type information to the context of cloud functions. Although this can be implemented locally, I prefer to implement it uniformly within the SDK.

### 🎤 Pitch

Using TypeScript but the context is still untyped doesn't make sense. And providing a better, simpler type annotation is all that's needed.
