Minimal API renames in RC 2

To improve the consistency of type names, two classes were renamed, and one class was removed and its methods merged into the existing xref:Microsoft.AspNetCore.Builder.EndpointRouteBuilderExtensions class.

Version introduced

ASP.NET Core 6.0 RC 2

Old and new behavior

• The Microsoft.AspNetCore.Builder.DelegateEndpointConventionBuilder class was renamed to xref:Microsoft.AspNetCore.Builder.RouteHandlerBuilder?displayProperty=fullName.
• The Microsoft.AspNetCore.Http.OpenApiDelegateEndpointConventionBuilderExtensions class was renamed to xref:Microsoft.AspNetCore.Http.OpenApiRouteHandlerBuilderExtensions?displayProperty=fullName.
• The Microsoft.AspNetCore.Builder.DelegateEndpointRouteBuilderExtensions class was removed and all of its methods were merged into the existing xref:Microsoft.AspNetCore.Builder.EndpointRouteBuilderExtensions?displayProperty=fullName class.

Change category

This change affects binary compatibility and source compatibility.

Reason for change

This change was made to improve the consistency of type names. Now that there is a new xref:Microsoft.AspNetCore.Routing.RouteHandlerOptions class, we wanted to replace DelegateEndpoint with RouteHandler.

Recommended action

Recompile any projects built with an earlier SDK. For most projects, this should be all that's necessary.

If your code references any of these type names directly by name, updated the code to reflect the new names.
