aspnet:8.0 image missing iputils-ping package

### Describe the bug

I have a Service running in a container of `mcr.microsoft.com/dotnet/aspnet:8.0`. This Sevice does a Ping using `System.Net.NetworkInformation.Ping` which is not possible because of this missing package.

I would expect that all provided core functionality from .NET works in these containers. Especially if it is the `System.Net` Namespace. So, I guess this is a bug.

My current workaround is the following in my Docker files:
```dockerfile
FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS base
RUN ["apt-get", "update"]
RUN ["apt-get", "install", "-y", "iputils-ping"]
```
But this increases the docker image build time and size considerably (15MB+) for such a small utility package.

### Which .NET image(s) are you using?

mcr.microsoft.com/dotnet/aspnet:8.0
