Lock datasets version

[courtney-sims]

Description

This change resolves dependency errors I encountered when running the setup for Interactive_Neuroscope colab.:

The datasets package released version 2.19.2 on June 3 and this version causes dependency issues with other requirements, like google-colab 1.0.0 (which does not have a newer version). Pinning datasets to the previous 2.19.1 resolved the issue and allowed the setup to complete without error.

Type of change
