Ensure that our list of recipes is backwards compattm/duplicate_recipes

Prior to chef 12.2 we included unexpanded 'cookbook' names for default
recipes. In 12.2, we moved to expanded ('cookbook::default') names,
which broke some searches.
However, some of our users have now moved to searching for expanded,
so we need to cater for both.
Fixes #3767
