ASPNETCORE_URLS has the wrong value when publishing via k8s

Hi,

I'm not confident enough to file this as an issue, but this line gave me trouble when I tried to deploy to my cluster:

aspire/src/Aspire.Hosting.Kubernetes/KubernetesResource.cs

Line 189 in 03b49a3

EnvironmentVariables["ASPNETCORE_URLS"] = new(aspNetCoreUrlsExpression, $"http://+:${defaultPort}");

$"http://+:${defaultPort}" produces the value "http://+:$8080" and I had to remove the $-sign in front of the port to make it work.

Am I doing something wrong or is this a bug?

We should be able to delete this code altogether. The project resource handles injecting the right environment variables.
