Running podman in podman results into an error to get to DNS server

Issue Description

My gitea runner is using podman, and I want to use podman inside (to build and test my containers) as well. To this end, I am building the image used by the runner as:

FROM quay.io/podman/stable

RUN dnf install -y git nodejs && \
    dnf clean all && \
    rm -rf /var/cache/yum

ADD --chmod=755 https://github.com/docker/compose/releases/download/v2.27.1/docker-compose-linux-x86_64 /bin/docker-compose

USER podman
WORKDIR /home/podman

Then, I am running a task on the runner as:

jobs:
    build:
        runs-on: podman
        container:
            volumes:
                - /mnt/act_runner/buildah-cache:/var/tmp/buildah-cache-1000
        steps:
            - name: Checkout
              uses: actions/checkout@v4

            - name: Login to registry
              run: |
                  podman login -u myuser -p ${{ secrets.RUNNER_LDAP_PASSWORD }} myregistry.org

            - name: Build
              run: |
                  hash=${{ env.GITHUB_SHA }}
                  podman build -t app/app:acc --build-arg GIT_COMMIT=${hash::8} --build-arg GIT_REF="${{ github.ref_name }}" -f docker/app/Dockerfile .

            - name: Test Unit/integration
              env:
                  DOCKER_HOST: unix:/run/podman/podman.sock
              run: |
                  echo "Building CI image"
                  podman build -t app/app:test -f docker/ci/Dockerfile .

                  echo "Running tests"
                  podman system service --time=0 &

                  podman info
                  docker-compose -f docker-compose.yml -f docker-compose.override.yml -f docker-compose.test.yml up app
                  docker-compose down -v

            - name: Push image to myregistry.org
              run: |
                  podman push app/app:acc docker://myregistry.org/app/app:acc

the podman commands run as expected, but for the docker-compose (which is pointing to podman socket, I have the same setup running locally for other containers), I am getting this error:

error during connect: Get "http://unix:2375/run/podman/podman.sock/v1.45/containers/json?all=1&filters=%7B%22label%22%3A%7B%22com.docker.compose.config-hash%22%3Atrue%2C%22com.docker.compose.project%app%22%3Atrue%7D%7D": dial tcp: lookup unix on 10.89.0.1:53: no such host

Steps to reproduce the issue

run the docker-compose command while inside the podman container run by Gitea

Describe the results you received

Describe the results you expected

The containers start as expected and my tests get run.
