Deployment fails with missing dependencies (`cgi`)

The website deployment fails during the build process [see](https://github.com/carbynestack/carbynestack.github.io/actions/runs/13067477253/job/36462266070) being unable to resolve required dependencies when installing mkdocs:

```sh
ModuleNotFoundError: No module named 'cgi'
```

According the gh-action logs, the job seems to use `Python 3.13.1`, however, it seems like the `cgi` module was removed since Python 3.13 (see [stackoverflow](https://stackoverflow.com/a/79022776)).

It seems like there are two options to fix the build:

1. Use and fix deployment task to use an older python version (e.g. 3.12.8 as used for the latest successful deployment)
2. Check and update dependencies for releases that support latest python version
