Update `travel-sample` sample dataset bundled in the Beta software package

Tracking ticket to update the bundled travel-sample dataset in Cheshire Cat Beta. 

While discussions related to the sample dataset are in progress for future milestones, not having an updated sample dataset in the public Beta build will lead to a poor user experience. Hence request updating the `travel-sample` dataset (for Beta) to add named collections and a named scope. This is to ensure that all documentation examples (old and new) work OOTB.
