`BeforeResourceStartedEvent` is not re-fired when application is restarted

[afscrome]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

The BeforeResourceStartedEvent event only gets fired the FIRST time a resource is started, and not on subsequent starts.

Expected Behavior

When restarting an application in the dashboard, the BeforeResourceStartedEvent should get fired twice (+ additional times if you restart the application more than once)

Steps To Reproduce

1. Have the below app
2. In the aspire dashboard, stop the one resource
3. In the aspire dashboard, start the one resource

var one = builder.AddContainer("one", "nginx");

builder.Eventing.Subscribe<BeforeResourceStartedEvent>(one.Resource, (evt, ct) =>
{
    Console.WriteLine("BeforeResourceStartedEvent");
    Console.Beep();
    return Task.CompletedTask;
});

Exceptions (if any)

@davidfowl What about ResourceReadyEvent? Should that fire when a resource is restarted?

Its documentation says that it fires the first time a resource is ready. But I'm guessing that is to handle the situation of the resource moving in and out of a healthy state after it launches, which is different than becoming healthy again after restarting.

@JamesNK I think you are right. We'll need to change the state tracking around the health checks for this.
