Sorting out Admiral Kuznetsov-related tags

BUR #35299 has been approved by @evazion.

rename admiral_kuznetsov_class_aircraft_carrier -> kuznetsov-class_aircraft_carrier
rename admiral_kuznetsov -> admiral_kuznetsov_(aircraft_carrier)
create implication admiral_kuznetsov_(aircraft_carrier) -> kuznetsov-class_aircraft_carrier
create implication liaoning_(aircraft_carrier) -> kuznetsov-class_aircraft_carrier
create implication shandong_(aircraft_carrier) -> kuznetsov-class_aircraft_carrier

In real life, the ship class that the Admiral Kuznetsov and her Chinese sisters belongs to is known simply as the Kuznetsov-class. Therefore it would make sense that the tag for the class should be renamed accordingly. Also adding a proper qualifier for Kuznetsov the ship and imply the ship with the class tag.

The bulk update request #35299 (forum #329412) has been approved by @evazion.

We don't normally tag the ship's class (e.g. we don't have an umbrella tag for Iowa-class battleships). Here it only seems necessary because the actual ship isn't identifiable in a few cases. I don't want to get into a habit of making umbrella tags for every ship class though.
