How do you install the latest version of the NNS / SNS with "dfx extension install"

,

We are in the process of retiring II build flavors, so there will be just one Wasm for development and production. The latest version of DFX doesn’t yet come with the version of PocketIc that has the new Wasms, stay tuned.

In the meantime, see you might find this announcement helpful: `internet_identity_frontend` is now a pullable DFX dependency

And if you go the manual route, please pick the Wasms from this release.
