[Documentation] Train/Test split in tutorials

[JulianKlug]

Location of the documentation

Tutorial example: https://temporai.readthedocs.io/en/latest/user_guide/usage/tutorial06_treatments.html#Using-a-temporal-treatment-effects-plugin.

tempor.data.dataset module: https://temporai.readthedocs.io/en/latest/api/tempor.data.dataset.html#tempor.data.dataset.BaseDataset.split

Documentation problem

Training and inference is done on the same data in all tutorials.

Suggested fix for documentation

Encourage train / test split in tutorials.
