Describe the bug

Related to the issue #18 , I create an empty config.json file with :
echo "{ \"auths\": {} }" > $HOME/.docker/config.json

The logout step "Removing registry credentials from" doesn't work, my config file always contain the credential but the logout action is OK.

Steps to reproduce, workflow links, screenshots

      - name: Log in to docker.io
        uses: redhat-actions/podman-login@v1
        with:
          username: ${{ env.REGISTRY_USER }}
          password: ${{ env.REGISTRY_PASSWORD }}
          registry: ${{ env.IMAGE_REGISTRY }}

More test

Also I tested with sample config with the same result :

echo "{ \"auths\": { \"dummy\": {} } }" > $HOME/.docker/config.json
