Hello World code sample in README.md is not properly awaited

[Programmer-RD-AI]

What happened?

The Hello World code sample provided in the README.md file of the repository does not properly await the asynchronous agent.run() method. This results in a RuntimeWarning and improper execution of the sample code.

<coroutine object BaseChatAgent.run at 0x75adf0cbb2e0>  
/home/ranuga/Jobs/Altrium/Altrium-PD/Learning/AutoGen/basic.py:7: RuntimeWarning: coroutine 'BaseChatAgent.run' was never awaited  
  print(agent.run(task="Say 'Hello World!'"))  
RuntimeWarning: Enable tracemalloc to get the object allocation traceback  

What did you expect to happen?

The code sample should execute correctly without raising a warning, and it should print the result of the task Say 'Hello World!'.

How can we reproduce it (as minimally and precisely as possible)?

1. Clone the repository and follow the setup instructions in the README.md.
2. Copy the Hello World code sample from the README.md.
3. Run the code without modifying it.
