image load into kind is not working when image is built with podman

Because the image loader is using `kind load docker-image` which is infected by https://github.com/kubernetes-sigs/kind/issues/2038 the image loading doesn't work when kind is started with podman. The builder can easily be utilised to use podman by setting `DOCKER_HOST` to a podman socket like described in https://github.com/GoogleContainerTools/skaffold/issues/8430#issuecomment-1612221929.

This can be fixed by using the concept described in https://github.com/kubernetes-sigs/kind/issues/2038#issuecomment-2889329040.
