indexing von chemotion repository for google dataset search

[tilfischer]

An enhancement request on the findability of dataset in Chemotion Repository:

For the N4C deliverable for Lead-by-Example we searched for datasets of authors via different search services. We noticed, that dataset in Chemotion Repository cannot be found by google dataset search, while datasets at MassBank EU were already indexed and are findable.
