Show Marketplace items in the categories

Currently, Qt Creator shows all marketplace items in one single view. We would need a more convenient way to filter / organise items. 

Marketplace itself organises items into collections. We could provide similar UI in Qt Creator to let the user see items in different collections. 

Shopify provides a REST API to read collections and items in each collection
