Migration project

[WolfgangFahl]

The migration issues https://github.com/SmartDataAnalytics/OpenResearch/issues?q=is%3Aissue+is%3Aopen+label%3AMigration that are labeled as automation https://github.com/SmartDataAnalytics/OpenResearch/issues?q=is%3Aissue+is%3Aopen+label%3Aautomation shall be handled with code from this repository. Therefore we'll add unit tests for testing. The unit tests will depend on a current wikibackup of openresearch created with

wikibackup -s or --progress -q "[[Modification date::+]]" -qd 10 

In the CI pipeline we'll have to resort to using only a few examples for testing which will have to be explicitly mentioned in the corresponding ticket.
