CI/CD

1. Branch 규약에 맞춰 branch 생성하여 개발
2. PR 생성 시 Spring test 실행
3. Codecov를 통한 coverage 검사 후 만족 시 main branch로 merge
4. Dockerfile에 따라 GitHub Actions를 통한 container image build 후 ghcr.io에 배포 (ghcr.io/co-co-gong/co-co-gong-server:latest)
5. GitHub SHA를 k8s manifest에 변경 (container image tag)하여 Argo CD에서 자동 배포 수행
