Github disables 'download data' workflow

[hugobuddel]

Github disables the 'download data' workflow with this message:

This scheduled workflow is disabled because there hasn't been activity in this repository for at least 60 days. Enable this workflow to resume scheduled runs.

However, we need this workflow, because it is

• automatically fetching data used by the other tests, and
• the only test that calls all the other libraries with internet access.

So we need to figure out how to prevent github from disabling this.

For now I'm manually enabling it again.
