Description of the feature request:

With the introduction of the new Google ADK, it seems beneficial to organize related examples effectively. I'd like to propose creating a dedicated subfolder within the main examples directory, perhaps named google-adk.

The idea is for this folder to host a series of notebooks demonstrating how to integrate ADK in various use cases, potentially showing how it works alongside the Gemini API.

If this organizational approach makes sense to the maintainers, I'd be happy to prepare an initial Pull Request. This first PR could create the folder structure, add a basic README explaining the folder's purpose, and include a simple "hello world" style demo notebook to get things started.

What problem are you trying to solve with this feature?

Having a dedicated folder could help to:

• Separate examples specifically focused on Google ADK integration from other general demos.
• Make it easier for contributors to find where to add new ADK-related examples and understand the expected structure.
• Provide users with a focused area for learning about ADK-based workflows and state management patterns.

Any other information you'd like to share?

I see this as a potential first step. If this structure is adopted, future contributions could build upon it by adding more complex and detailed demos and notebooks. Creating a new subfolder now could provide a good foundation for organizing all future ADK-related examples within the repository.

Would be grateful for feedback on this suggestion!
