Fix example for LLM configuration docs

[jackgerrits]

Why are these changes needed?

The current simplest example does not work as the OpenAI client complains that "model" is not defined in the request.

Great catch!

There is another issue perhaps related to this PR. When I run the following command outside of the project repo direcotry:

>>> import autogen
>>> config_list = autogen.get_config_list(["test"], api_type = "openai")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: module 'autogen' has no attribute 'get_config_list'

It is complaining about the import issue. Could be related to #1526

This can happen when you have an "autogen" directory in the current path. If you import it from other places it works.
