Permission to denied error when deploying

Hi,
thanks for developing and maintaining this tool.

I am trying to use it for a repository that I contribute to. So far, my effort has been unsuccessful. I am getting an
```
remote: Permission to SlicerDMRI/SlicerDMRI.git denied to github-actions[bot].
fatal: unable to access 'https://github.com/SlicerDMRI/SlicerDMRI.git/': The requested URL returned error: 403
```

error at the moment where the deployment should take place: https://github.com/SlicerDMRI/SlicerDMRI/actions/runs/6685911043/job/18164701923?pr=195#step:2:787

I have granted write permissions to the workflow, actions do have write permissions in the repository settings, and the GitHub pages `Build and deployment` is configured to deploy from the `gh-pages` branch; I have also tried setting it to `GitHub Actions` with the same result.

What am I missing?

Thanks.
