Possible merge issue with 0.0.31 release

[jonbaiernx]

The example on this page appears to want version 0.0.31 to use local models. https://github.com/whylabs/langkit/blob/main/langkit/examples/Local_Models.ipynb

However, it looks like the code to make this happen is only in the main branch and not in the 0.0.31 release. When trying to run the example with latest pip install I get the old error about an unrecognized model.
