AI-300: Updated lab instructions and fixes for GenAIOps labs

Summary

While completing the AI-300 GenAIOps labs, I encountered several issues that caused deployment failures, authentication problems, and workflow blockers that required significant troubleshooting.

To help future learners, I have prepared updated guidance, fixes, and clarifications in:

updated-instructions-ai-300-genaiops

Changes Included

• Added guidance for purging soft-deleted Azure AI Foundry resources before running azd up
• Fixed .env file generation instructions for Windows PowerShell to avoid UTF-16 encoding issues
• Added OIDC authentication guidance, including required federated credentials for both branch and pull request workflows
• Documented required Azure role assignments and permission verification steps
• Clarified branch, deployment, and evaluation workflows
• Added guidance for creating and scoring evaluation.csv
• Added Git setup instructions (user.name and user.email)
• Added guidance for cloning private template repositories and working with feature branches and pull requests

Benefits

These updates reduce learner troubleshooting time, address common environment and authentication issues, and improve the overall learning experience by allowing learners to focus on GenAIOps concepts rather than lab setup and debugging.
