fix(topology): admin-rocketchat — drop NTP-and-update-time from basic_packages

In an egress-filtered / air-gapped range udp/123 is blocked (even the Proxmox
node can't NTP-sync), so software.install.warmup.basic_packages' hard
"wait for NTPSynchronized == yes" never succeeds and fails stage_01. Don't
enable NTP sync for this box; VMs take host (kvm-clock) time.
