nmcli regression: can't set IPV6 token

[Charles Hedrick]

24.04 nightly, downloaded Mar 5.

network-manager 1.45.90-1ubuntu1

In network manager, if you try to set ipv6.token, when you save it says

Error: connection verification failed: ipv6.token: only makes sense with EUI64 address generation mode

This is the same as under 22.04. However under 22.04 the solution is setipv6.addr-gen-mode eui64 along with the token. In 24.04 when you save you get

Error: Failed to save 'netplan-enp3s0' (6effa1b1-280b-3785-9b52-c723b445fb3e) connection: failed to update connection: netplan: YAML translation failed: Error in network definition: enp3s0: ipv6-address-generation and ipv6-address-token are mutually exclusive

There doesn't seem to be any combination involving the token that works.
