oh sorry, it is my first time to use mdx format, is there anyway I can preview the changes before commit?
I tried this extension, but it seems not working for me.

It is my first time to use mdx format and I do not know where I can preview the changes for mdx, so basically, the way I have done is copy-paste the previous content and changed to yaml version.

BTW, I have added pyyaml to setup.py to make sure no one get error when loading config, since we don't use json module but yaml.

Additionally, I have implemented pytest for the YAML version. Specifically, I utilized pytest.mark.parametrize to minimize code duplication.

See https://microsoft.github.io/autogen/docs/contributor-guide/documentation, the process_notebooks.py script will generate the MDX files.

We can add pyyaml to test dependencies. But for install dependency let's move this to an optional dependency like those below.

[ekzhu]

If the yaml dependency is not installed, we can fall back to use json module. We can do this by checking for yaml import error during import, and use that information to choose whether to use yaml load or json load.

[Mai0313]

oh, it sounds good

[ekzhu]

Add explanation for installing pyyaml.
