cproudlock 4d6438285b playbook: document USB-C 5 Gbps NIC bridge override on netplan task ...

The "Configure static IP for PXE interface" task writes a flat
single-NIC netplan config. Live PXE server (10.9.100.1) overrides
this with a bridge config bonding the USB-C 5 Gbps NIC and the
onboard NIC into br-pxe, because the onboard NIC alone cannot
sustain the imaging throughput required by the floor.

Add a comment block above the task warning that re-running it on
a box already using the bridge config will replace the bridge with
a flat single-iface config and likely break the PXE LAN. The full
bridge YAML is included for reference. Recovery is via
/etc/netplan/50-cloud-init.yaml.pre-gold-swap (preserved by netplan
backup).
