create implication belchan_(azur_lane) -> belfast_(azur_lane)
If this tag should stay it should imply the main tag (that's how it's currently being tagged with few exceptions), I should also be tagged together with younger but I'm not sure if we want to make that implication too.
EDIT: The tag implication belchan_(azur_lane) -> belfast_(azur_lane) (forum #147623) has been approved by @Hillside_Moose.
