2025-02-11: Evaluation scripts and workflow

For a long time, we've directed developers to follow the steps in ai-rag-chat-evaluator to run evaluations on this app. To make it easier, we've now integrated evaluation directly into the repository, both as CLI scripts and GitHub Actions workflow.

Learn more from the evaluation guide or watch this video about evaluation.
