[release/9.0] Drop Microsoft.AspNetCore.Grpc.Swagger

[Copilot]

Drop Microsoft.AspNetCore.Grpc.Swagger

This is a backport of #67919 which removes the experimental Microsoft.AspNetCore.Grpc.Swagger.

Description

See #67134

This package has been experimental with relatively low usage.

https://www.nuget.org/packages/Microsoft.AspNetCore.Grpc.Swagger -> Current version (released 23 days ago) 36K downloads.

In contrast, https://www.nuget.org/packages/Swashbuckle.AspNetCore.Swagger has 7.6M downloads for current version (released only a month ago), and https://www.nuget.org/packages/Microsoft.AspNetCore.OpenApi has 2M downloads for current version (released 23 days ago).

The package adds maintenance cost that's not worth it.

Pull request overview

Removes the deprecated Microsoft.AspNetCore.Grpc.Swagger package from the release/9.0 branch, including its source, tests, and all repo/build references, leaving gRPC JSON transcoding and built-in OpenAPI as the supported path.

Changes:

• Deleted the Microsoft.AspNetCore.Grpc.Swagger project and its PublicAPI files.
• Deleted the Microsoft.AspNetCore.Grpc.Swagger.Tests project (tests, protos, and helper infrastructure).
• Removed remaining references in build metadata and cleaned the JsonTranscoding Sandbox test asset to no longer configure Swagger.

@copilot Does AspNetCore.sln need to be updated to address the removal of the projects? Commit to this PR with the needed changes, if any.

Yes, AspNetCore.sln still had references to both removed projects. I've cleaned them up in the latest commit — removed the two Project(…) EndProject declarations, their 32 build configuration lines, and the 2 NestedProjects entries.
