[mqtt.espmilighthub] fix upgrade instructions (#16127)

since #13801, it's not been possible to add new milight things,
because the thing XML already has the new channel types, but not
the thingTypeVersion property set, so it would try to apply the
update instructions and error about duplicate channels
