Bump Microsoft.Extensions.Caching.Hybrid and 3 others

[dependabot]

Updated Microsoft.Extensions.Caching.Hybrid from 10.4.0 to 10.5.0.

Release notes

Sourced from Microsoft.Extensions.Caching.Hybrid's releases.

10.5.0

HTTP Logging Middleware APIs in Microsoft.AspNetCore.Diagnostics.Middleware are now stable. This release also transfers Microsoft.Extensions.VectorData.Abstractions and Microsoft.Extensions.VectorData.ConformanceTests from the Semantic Kernel repository into dotnet/extensions, jumping from 10.1.0 to 10.5.0 for consistent versioning. The release also delivers fixes across the AI libraries, AI Evaluation, and Service Discovery.

Breaking Changes

1. Rename VectorStoreVectorAttribute constructor parameter #​7460
   • The Dimensions parameter was renamed to dimensions (lowercase). This is a source-breaking change only — binary compatibility is preserved.
   • If you use the named argument syntax new VectorStoreVectorAttribute(Dimensions: 1536), update it to new VectorStoreVectorAttribute(dimensions: 1536).

Experimental API Changes

Now Stable

• HTTP Logging Middleware APIs are now stable (previously EXTEXP0013): AddHttpLogEnricher<T>, IHttpLogEnricher, and RequestHeadersLogEnricherOptions.HeadersDataClasses #​7380
