Describe the bug

K3SContainer calls get_container_host_ip in its __init__ method here and here before the container is started, causing it to fail with an AssertionError here.

To Reproduce

from testcontainers.k3s import K3SContainer

with K3SContainer() as k3s:
     print("gonna throw an error before I even get here :(")

Runtime environment

I'm on an ARM Mac and this is in Python 3.12, but that shouldn't make a difference.
