Economy API docs (mostly) don't specify economy version

[kevinfoley]

The Catalog - Search Items page indirectly mentions (through a URL) that the function relates to Economy V2: https://learn.microsoft.com/en-us/rest/api/playfab/economy/catalog/search-items?view=playfab-rest

However, most other pages don't specify the economy version. Even the Overview page doesn't specify whether it relates to legacy Economy or Economy v2: https://learn.microsoft.com/en-us/rest/api/playfab/economy/catalog?view=playfab-rest
