Pi OS must not be using NetworkManager.  It may be using
systemd-networkd instead.  Or something else.  In any case, you should
be able to get local-network-pingable.service to work without using
NetworkManager-wait-online.service.  Just ignore anything in the
instructions that refers to NetworkManager-wait-online.service.
