Set https redirection port

[affand]

The app use UseHttpsRedirection() to enforce https. However no https port for redirect specified. So we need to add one in Startup.cs

services.AddHttpsRedirection(options =>
            {
                options.RedirectStatusCode = StatusCodes.Status307TemporaryRedirect;
                options.HttpsPort = 5001;
            });

AFAIK, explicit Https port declaration is optional because ASP.Net Core will smartly provide the port for us. If we want to customize the port, I prefer to do it via env var ASPNETCORE_HTTPS_PORT.
