Missing tgz package file on gh-pages branch.

[yunwz]

I'm using chart-releaser-actoin(v1.7.0) to publishing tgz package file and index.yaml file.
This is the github action config in my github repository (https://github.com/YunWZ/nacos-k8s/blob/92a42759ca005c8e502787914ddc46600eda395a/.github/workflows/release.yml):

...
      - name: Run chart-releaser
        uses: helm/chart-releaser-action@cae68fefc6b5f367a0275617c9f83181ba54714f # v1.7.0
        with:
          skip_existing: false
          charts_dir: 'charts'
          packages_with_index: true
          pages_branch: gh-pages
        env:
          CR_TOKEN: "${{ secrets.GITHUB_TOKEN }}"
          CR_GENERATE_RELEASE_NOTES: true
...

And the flowing context is the latest runed job output:

I had noticed the index.yaml file has been uploaded to gh-pages branch, but acos-1.0.0.tgz did't upload to gh-pages branch. Why?
