Pull request overview

This PR fixes an issue with scoped ASP.NET health checks by ensuring that a service scope is created for each health check execution, matching ASP.NET's HealthCheckService behavior. It also corrects documentation that incorrectly stated health contributors were registered as scoped services when they are actually singletons.

Key changes:

• Modified HealthAggregator to create a service scope for each Microsoft health check execution, enabling support for scoped dependencies
• Corrected XML documentation comments in EndpointServiceCollectionExtensions to accurately reflect that health contributors are registered as singleton services
• Enhanced test infrastructure to validate service scopes and added a comprehensive test for scoped health checks using Entity Framework Core
