Table: Update pagination demo data

[jenny-s51]

Rename Bulk Select to "Pagination with Bulk Select" and add a description underneath that explains that (default) Pagination is used with an external API. If the consumer is working with an external API, default Pagination will programmatically fetch data based on the page and perPage parameters in the URL. Can leave the general structure of the data/demo as-is.
