13.1.0 can no longer resolve cosmosDb connection string from resource

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the bug

I have an app that connects with CosmosDb.

It declares cosmosDb resources:

```csharp
ar cosmosDbAccount = builder.AddAzureCosmosDB(name).WithAccessKeyAuthentication(); // Using access key to facilitate EF core migrations.
var cosmosDbDatabase = cosmosDbAccount.AddCosmosDatabase(Config.CosmosDbDatabaseResourceName, Config.CosmosDbDatabaseName);
```

And my project has a reference to the cosmosDbAccount (though I've tried referencing 'cosmosDbDatabase' as well).

This was working fine with Aspire 13.0.2. After updating to 13.1.0, my cosmos db resource appears fine on the dashboard (can see the connection string), but my projects referencing it fail to start, the console logs seem to simply show them stuck waiting:

> Waiting for value for connection string from resource 'cosmosDb'
> Waiting for value from Aspire.Hosting.ApplicationModel.ReferenceExpression.

There's no other detail or output anywhere.

### Expected Behavior

Connection to cosmosDb should continue to work as before in 13.0.2.

### Steps To Reproduce

It's just an aspire project with one web project referencing a cosmosdb resource as described above. I don't know if it relates to me using 'WithAccessKeyAuthentication' and something getting more strict/locked out on that front, but I couldn't see mention of anything in breaking changes.

### Exceptions (if any)

Minimal output from Aspire, just what I've described above.
