Hi
You are using v3 as the v1 and v2 are deprecated and they are not seen in Azure Portal. The description does not mention that this is v2 version. It mentions that recommendations from v2 are within this initiative. Never the less all the built-in policies and initiatives are available in this repository. If you see any issues with the description you can post an issue in that repository.
Please "Accept the answer" if the information helped you. This will help us and others in the community as well.
