fix: use host networking for interop tests in CI

Docker's default bridge network causes Zenoh service/topic discovery
to fail due to localhost communication limitations. Using host networking
resolves this issue and allows proper communication between ROS2 and
ros-z components.

Tests pass successfully on bare metal and with Docker host networking.
