fix: litellm structured_output test with more descriptive model

[dbschmigelski]

Description

Our integ test has been failing for some time. I am not certain what changed but my expectation is it is the quality of the underlying model. To fix this I made the pydantic model more descriptive. I am comfortable with this rather than diving deeper on a fix because the change did not modify our test logic at all. Rather, this simply provides more context to the llm.
