Fix documentation: Replace non-existent DataSourceGeneratorProperty with ClassDataSource<T>

 ## The Solution
 
-TUnit automatically initializes nested data sources in the correct order using the `[DataSourceGeneratorProperty]` attribute.

+1. TUnit detects properties marked with data source attributes (like `[ClassDataSource<T>]`)
 2. It builds a dependency graph and initializes in the correct order
 3. Each object's `InitializeAsync` is called after its dependencies are ready
 4. Disposal happens in reverse order automatically
 
 ## Best Practices
 
 1. **Implement IAsyncInitializer**: For any class that needs async initialization
-2. **Use DataSourceGeneratorProperty**: To declare dependencies that must be initialized first
+2. **Use Data Source Attributes**: Use attributes like `[ClassDataSource<T>]` to declare dependencies that must be initialized first
 3. **Share Expensive Resources**: Use `SharedType` attributes to avoid creating multiple containers
 4. **Dispose Properly**: Implement `IAsyncDisposable` for cleanup
 5. **Keep Initialization Fast**: Do only essential setup in `InitializeAsync`

 ## Key Points
 
-✅ **Automatic Initialization**: Properties marked with `[DataSourceGeneratorProperty]` are initialized before `InitializeAsync` is called
+✅ **Automatic Initialization**: Properties marked with data source attributes (like `[ClassDataSource<T>]`) are initialized before `InitializeAsync` is called
 
 ✅ **Proper Order**: TUnit handles the dependency graph and initializes in the correct order
