[13.3] `aspire run` and `aspire start` behave differently if `DisableDashboard = true`

[afscrome]

Is there an existing issue for this?

Describe the bug

Expected Behavior

If aspire start can start the app host, I'd also expect aspire run to do so.

I'd also expect both to be able to start an apphost when the dashboard is disabled as I could use the aspire CLI commands to interact with the app host instead of the dashboard. The same app can be started successfully with dotnet run apphost.cs

Steps To Reproduce

#:sdk Aspire.AppHost.Sdk@13.3.0

var builder = DistributedApplication.CreateBuilder(new DistributedApplicationOptions
{
    DisableDashboard = true
});

builder.AddContainer("nginx", "nginx");

builder.Build().Run();

Exceptions (if any)

Not high impact. Fix in 13.4.
