Add patterns examples to storybook

[cal-smith]

Storybook supports grouping stories and creating a heirachy of stories: https://storybook.js.org/docs/basics/writing-stories/#story-hierarchy

For example, we may have a "Patterns|Filtering" set of stories

ideally we should have (at minimum) one story for each pattern listed here: https://www.carbondesignsystem.com/patterns/overview
