Flakey tests if running Tests `WithEndpointProxySupport(false)` in parallel

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the bug

If you have a persistent container, and run `DistributedApplicationTestingBuilder` tests in parallel, the two instances race to create the persistent containers and end up in a very confused state.

### Expected Behavior

Aspire shouldn't try to provision the persistent container multiple times.

### Steps To Reproduce

Run any instance of the below test by itself, the test will pass. Run both together, and the test hangs.
```cs
#pragma warning disable ASPIREPROXYENDPOINTS001 // Type is for evaluation purposes only and is subject to change or removal in future updates. Suppress this diagnostic to proceed.
[assembly: Parallelizable(ParallelScope.All)]

public class WebTests
{
[TestCase(1)]
[TestCase(2)]
public async Task Test(int instance)
{
var cts = new CancellationTokenSource(TimeSpan.FromSeconds(60));

var builder = DistributedApplicationTestingBuilder.Create();

var sql = builder.AddSqlServer("sql")
.WithHostPort(12345)
.WithEndpointProxySupport(false)
.WithLifetime(ContainerLifetime.Persistent);

var app = builder.Build();

await app.StartAsync(cts.Token);
await app.ResourceNotifications.WaitForResourceHealthyAsync(sql.Resource.Name, cts.Token);
}
}
#pragma warning restore ASPIREPROXYENDPOINTS001 // Type is for evaluation purposes only and is subject to change or removal in future updates. Suppress this diagnostic to proceed.
```

### Exceptions (if any)

The output varies from run to run, but there's the example of both tests from one run
