docs: remove outdated Docker Compose references

The repository does not include docker-compose files, but multiple docs
claimed "Docker Compose deployment out of the box." This was left over
from a previous release.

Changes:
- README.md: Update FAQ to describe Python package deployment
- README.ko.md: Same update for Korean translation
- docs/configuration.md: Remove "Docker Compose Integration" section
  and docker compose commands
- docs/quizzes: Update tasks that referenced docker-compose.yml
- .github/CODEOWNERS: Remove docker-compose*.yml entry
- scripts/setup.sh: Remove docker-compose.override.yml copy step

Fixes aden-hive#923
