Have IErrorNotifier served by DI

#183

[freerider75]

With this change the error notifiers are removed from options and handled by dependency injection.
An example of the new way of configuring error notifiers:

builder.Services.AddTransient<IErrorNotifier, MyNotifier>();  // <-- just add one or more IErrorNotifier registrations, they will be passed to ErrorLogMiddleware
builder.Services.AddElmah<XmlFileErrorLog>(options =>
{
    options.LogPath = "~/log";
    options.Filters.Add(new CmsErrorLogFilter());
});
