• Documentation in docs is updated

Description of changes

I have added the full cinemaot dataset (9209 cells). Previously, only a subsampled version was available through pt.dt.cinemaot_example(). However, to provide an example for the cinemaot.synergy() method, we need the full dataset because it contains cells with all three stimulations, while the subsampled version contains only one stimulation.

The subsampled dataset is still available via pt.dt.cinemaot_example(), the full dataset can now be obtained using pt.dt.cinemaot_full().

Great!

On a second thought we should rename it to dong_2023 instead of cinemaot_full?
