nixos/doc: improve release notes for iptables-nft and systemd with nftables backend
This change probably wasn't documented sufficiently in the release
notes, neither the fact systemd stopped using iptables on its own in
case of nf_tables support.
Fixes #156041.
(cherry picked from commit 753a43caf07790a923d8f6394744f1c5b0eb8ee4)
