The ip returned by `socket.gethostname()` is default docker `172.21.0.1` ip, which is not the actual IP of the host. Replace `socket.gethostname()` with `host.docker.internal`.

Problem: The Django Debug Toolbar does not display in Docker (tested on MacOS) because
socket.gethostname()returns Docker's default IP (172.21.0.1), not the host's IP.Solution: Switch
socket.gethostname()tohost.docker.internalto accurately reference the host machine's IP from within Docker containers. This change ensures the the host's IP is added to INTERNAL_IPS and the Django debug toolbar is visible when developing in Docker.
