Add a new sample to show streaming and R1 usage (#5285)

* New sample of chess playing showing R1's thought process in streaming
mode
* Modify existing samples to use `model_config.yml` instead of JSON
configs for better clarity.

+# AgentChat Chess Game
+
+This is a simple chess game that you can play with an AI agent.
+
+## Setup
+
+Install the `chess` package with the following command:
+
+```bash
+pip install "chess"
+```
+
+To use OpenAI models or models hosted on OpenAI-compatible API endpoints,
+you need to install the `autogen-ext[openai]` package. You can install it with the following command:
+
+```bash
+pip install "autogen-ext[openai]"
+# pip install "autogen-ext[openai,azure]" for Azure OpenAI models
+```
+
+Create a new file named `model_config.yaml` in the the same directory as the script
+to configure the model you want to use.
+
+For example, to use `gpt-4o` model from OpenAI, you can use the following configuration:
+
+```yaml
+provider: autogen_ext.models.openai.OpenAIChatCompletionClient
+config:
+  model: gpt-4o
+  api_key: REPLACE_WITH_YOUR_API_KEY
+```
+
+To use a locally hosted DeepSeek-R1:8b model using Ollama throught its compatibility endpoint,
+you can use the following configuration:
+
+```yaml
+provider: autogen_ext.models.openai.OpenAIChatCompletionClient
+config:
+  model: deepseek-r1:8b
+  base_url: http://localhost:11434/v1
+  api_key: ollama
+  model_info:
+    function_calling: false
+    json_output: false
+    vision: false
+    family: r1
+```
+
+For more information on how to configure the model and use other providers,
+please refer to the [Models documentation](https://microsoft.github.io/autogen/stable/user-guide/agentchat-user-guide/tutorial/models.html).
+
+## Run
+
+Run the following command to start the game:
+
+```bash
+python chess_game.py
+```
+
+By default, the game will use a random agent to play against the AI agent.
+You can enable human vs AI mode by setting the `--human` flag:
+
+```bash
+python chess_game.py --human
+```
