Issue:
Datasets fetchers bids_langloc and language_localizer_demo seem to be getting the same data
LLooking at the data from those 2 datasets, I am not sure I can tell the difference between the 2?

Events files look kind of similar.

- fetch_bids_langloc_dataset
- fetch_language_localizer_demo_dataset

Also the bids_langloc_dataset seems unused in our examples.

I have not checked that every file is **exactly** the same for both datasets except for the filename but I would say, it would still make sense to start deprecating the `bids_langloc` and point users to the other dataset.
I would also be in favor of deprecating one. If bids_langloc is not used in an example and there is no good argument to add it somewhere, I don't see a reason to keep it.
