As part of SERVER-79496 we banned encryption options from being passed to the createCollection command starting on 7.2.

We wrote this check without an FCV guard. This turns out to break the FCV guarantee since a mixed version replicaset with the same FCV will have different behaviour of nodes. One node would fail, while another succed.

We should wrap this in a feature flag that's already enabled starting on 7.2 in order to get proper mixed version support.
