This issue is for tracking the UI implementation of the categorized connector gallery.

At the highest level it appears we'll need to create a new component for the category list. Most likely we'll need to refactor the current gallery view implementation a bit, and now would be a great time to ensure there are storybook entries for these components.

One other item to investigate is implementing the on-demand fetching of pages and migrating the current paginated view to that, i.e. is there already a component that implements this that we can adopt.
