`GetEnvironmentVariableValuesAsync ` doesn't properly resolve `HostUrl`

[afscrome]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

resource.GetEnvironmentVariableValuesAsync() doesn't pass through AppHost:ContainerHost down into ProcessEnvironmentVariableValuesAsync, and so always resolves host references as host.docker.internal

Expected Behavior

I'd expect it to honour AppHost:ContainerHost, but with this extension method on IResource, it doesn't have any reference to the Configuration. This seems very similar to #9787 , which makes me wonder if the API itself is the problem - needing to be on a supporting service rather than an extension method on IResource. So whilst it's a good approximation, there are a number of edge cases where it will resolve values differently.
