parsing networkctl interface output for DHCPv4 address broken w/ systemd v256

Systemd v256 changed the networkctl status <link> output line so that networkd-dispatcher's normalization (https://gitlab.com/craftyguy/networkd-dispatcher/-/blob/7ff0b32b21890075e3f816316b3865e88200e75c/networkd-dispatcher#L124-126) of the address doesn't work properly anymore, because the networkctl output line reads "DHCPv4" rather than "DHCP4"

% networkctl status eno1 | grep '  Address:'
                     Address: a.b.c.d (DHCPv4 via e.f.g.h)
% % networkctl --version

This results in an ADDR being passed via environment to scripts looking like: a.b.c.d (DHCPv4 via e.f.g.h)
