Resolves #5192

Test

AutoGen AgentChat

AgentChat is a high-level API for building multi-agent applications. It is built on top of the autogen-core package. For beginner users, AgentChat is the recommended starting point. For advanced users, autogen-core's event-driven programming model provides more flexibility and control over the underlying components.

AgentChat provides intuitive defaults, such as Agents with preset behaviors and Teams with predefined multi-agent design patterns.
