Create trigger_ha_addon.yml

Action for ha-addon container build trigger in wmbusmeters/wmbusmeters-ha-addon repo.
This should be accepted after secrets has been configured in all related repos.
Starting from now all ha-addon changes should go to wmbusmeters/wmbusmeters-ha-addon repo and should not be accepted here.
After next release I will make changelog changes to inform users to switch to new repo.
