UseStatusCodePagesWithReExecute method original context handling unclear

### Description

Example, on this same page there is a point to mention:
> For the [UseExceptionHandler(IApplicationBuilder, String)](https://learn.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.builder.exceptionhandlerextensions.useexceptionhandler#microsoft-aspnetcore-builder-exceptionhandlerextensions-useexceptionhandler(microsoft-aspnetcore-builder-iapplicationbuilder-system-string)) overload that is used in templates, only the request path is modified, and the route data is cleared. Request data such as headers, method, and items are all reused as-is.

However for the UseStatusCodePagesWithReExecute extension method it does not clarify this point. Specifically I was trying to verify how to see the original http method and referrer during the custom handling. Through trial and error I was able to verify that the http method and the referrer are preserved and I could simply get the values from the HttpContext.Request. This documentation would be incredibly helpful with this update.
