Have docker nginx logs print the client IP

[joecorall]

Use realip nginx module to have docker logs print the client IP in its logs rather than the traefik private IP.

I made this code change in the GitHub Cloud IDE and inadvertently committed to the main branch: 78ab2d5 which I then reverted 95ecba3 (and canceled the GitHub Actions). Should we prevent direct pushes to main in this repo without a PR? When I clicked the "Commit" button in the GitHub IDE I thought it was going to prompt me to enter a branch name is how I made the mistake.

Before

$ docker compose logs drupal-prod --tail 5
