fix the problem config_list_from_dotenv() can't correctly get other p…

[Wannabeasmartguy]

Why are these changes needed?

As you can see, when I was testing the code shown below, I found that I couldn't get the configuration information saved in .env correctly with config_list_from_dotenv(). The version of pyautogen is 0.2.20, which is the latest release.

And my .env is like this:

Then I realized that get_config() was using the wrong parameter to get the configuration, and changed it to get the other parameters correctly.

After the modification, the code works fine.
