[x] I've formatted the new code by running poetry run pre-commit run --all-files --show-diff-on-failure before committing.
Description
Increases the number of data points for the hyperparameter inference example in the intro to kernels notebook -> makes it visually make more sense
factors out plot_ribbon function to simplify notebook (-> should we move this into a plotting_utils or some such? presumably it would be useful for more notebooks)
