Not clear which resources to start with ExplicitStart() and WaitFor()

### Is there an existing issue for this?

### Is your feature request related to a problem? Please describe the problem.

When you have two resources with an explicit start and resource 2 has to wait for resource 1 to start, you do not get any feedback in the dashboard what the resource is waiting for. You can look in the graph to find dependencies, but this becomes less obvious when you have a large number of resources.

It is in the logs, but this is not an obvious place to look.

### Describe the solution you'd like

The most simple solution would be to show a popup that tells you which resources also need to be started and would already be very helpful.

My preferred solution would be that Aspire is starting the required resources as they need to be running anyway, but I can understand if the might be a step to far.
