@sverhoeven Would you have time to take a look at this?

I looked into the issue and the PDF can be generated locally without issues not as a GitHUb action with docsify-pdf-converter (we looked into alternatives and docker-docsify-pdf looked promising). It is difficult to test whether it can be pushed to Zenodo at the moment (the last step in the workflow). We can wait for the new release and fix it if it fails to publish the PDF to Zenodo.

The PDF generation itself has been fixed in #393. The only thing remaining for this issue is to check whether the upload to Zenodo is working when we publish the v1.0 release.

Hey @vedran-kasalica, @egpbos just did a release, but it looks like the PDF build is failing. Any idea what may be going wrong?
