rule `download_reich_1240K` now fails due to a change in the AADR dataset's hosting server.

[MaelLefeuvre]

Description

The old URL https://reichdata.hms.harvard.edu/pub/datasets/ where the AADR was hosted has now changed to https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/FFIDCW, with a new access API. (See: Dataverse API guide)

Proposed solutions:

• Update URL and conform badger to the new dataverse API
• Implement a CI/CD job to regularly check for URL validity
