Gigantamax Urshifu Implications

BUR #40697 is pending approval.

create implication gigantamax_urshifu -> urshifu
create implication gigantamax_urshifu_(rapid) -> urshifu_(rapid)
create implication gigantamax_urshifu_(rapid) -> gigantamax_urshifu
create implication gigantamax_urshifu_(single) -> urshifu_(single)
create implication gigantamax_urshifu_(single) -> gigantamax_urshifu

Urshifu is a bit of a complex Pokémon to tag, as it's the only one with multiple Gigantamax forms, corresponding to each of its two regular forms. A solo image of its Rapid Strike Gigantamax form, for instance, would requite four distinct tags: urshifu, urshifu (rapid), gigantamax urshifu, and gigantamax urshifu (rapid). I know there aren't very many posts of Gigantamax Urshifu to begin with, but this would help streamline things for people who upload art of it in the future.

BUR #40698 is pending approval.

create implication gigantamax_urshifu_(rapid) -> urshifu_(rapid)
create implication gigantamax_urshifu_(single) -> urshifu_(single)
nuke gigantamax_urshifu

Alternatively, we could just get rid of the umbrella tag. Someone looking for art of both Gigantamax forms could search "gigantamax_urshifu*" and get the same results, so I guess it is a bit superfluous.
