Pull request overview

This PR enhances the FinOps hubs recommendations feature by adding granular control over potentially noisy recommendation types, standardizing naming conventions, and improving the deployment experience through the Azure portal UI.

Changes:

• Added enableAHBRecommendations and enableSpotRecommendations parameters to allow users to opt-in to potentially noisy recommendations about Azure Hybrid Benefit and Spot VMs
• Renamed recommendation query files from HubsRecommendations-* to Recommendations-Microsoft-* pattern and updated metadata to use PascalCase (ResourceGraph, Tenant) instead of lowercase
• Added a new "Recommendations" tab to the Azure portal deployment UI (createUiDefinition.json) with clear descriptions of included and optional recommendations
• Changed enableRecommendations default to false to reflect preview status
• Improved code organization by using conditional query file loading with the union() pattern
