Purpose

This pull request updates dependencies across several requirements files to align with the latest versions and improve compatibility, especially for Azure SDKs and OpenTelemetry. The most important changes are grouped below by theme.

Dependency version updates:

• Upgraded azure-ai-projects from version 1.0.0b12 to 2.0.0b3 in content-gen/infra/vscode_web/requirements.txt to ensure compatibility with newer Azure AI Foundry features.
• Updated azure-ai-projects to version 2.0.0b3 in content-gen/src/backend/requirements.txt for consistency across environments.

Azure SDK and telemetry improvements:

• Added opentelemetry-semantic-conventions-ai==0.4.13 to content-gen/src/backend/requirements.txt to support OpenTelemetry tracing required by agent-framework.
• Added azure-search-documents>=11.4.0 to content-gen/src/backend/requirements.txt to provide search document capabilities for backend services.
• Removed azure-search-documents>=11.6.0 from content-gen/scripts/requirements-post-deploy.txt to centralize dependency management and avoid redundancy.
