feat(evaluate): Add Azure AI Evaluation & Observability Workshop Notebook

[thegovind]

Description

This PR adds a comprehensive workshop notebook demonstrating Azure AI's evaluation and observability capabilities, developed in collaboration with @changliu2 and Alex Sutton for TechConnect. This is the first iteration of the workshop material, which has been fully tested and provides hands-on examples of:

• Safety evaluation using ContentSafety, Violence, and HateUnfairness evaluators
• Security testing with DirectAttackSimulator and adversarial testing
• Quality assessment using Relevance, Coherence, and Groundedness evaluators
• Cloud-based evaluation workflows with azure-ai-projects
• Observability setup with OpenTelemetry and Application Insights
• Best practices for responsible AI governance

The workshop includes:

• A Jupyter notebook with detailed explanations and working code
• Sample evaluation test data in JSONL format
• Environment configuration templates

This serves as a practical guide for developers to implement comprehensive evaluation and monitoring in their Azure AI applications.
