This AI sample lacks risk & safety evaluation implementation

As per email sent on 13th Dec with same subject, please double-check that this AI sample implements evaluations. In particular, what we are looking for is:

• Evaluation file(s) (might be a Jupyter notebook, a unit test script, etc.) that evaluates the solution against quality metrics
• Evaluation file(s) (might be a Jupyter notebook, a unit test script, etc.) that evaluates the solution against at least 2 safety metrics
• A descriptive section in your readme explaining how evaluation is implemented into the sample.

@nitya Adding this issue here so we can track progress on the evaluation stream. I know you mentioned that one blocker is that existing evaluations should be migrated to the Azure AI eval SDK before adding more metrics.
