ginkgo -> ginkgo_tree alias

BUR #17062 has been approved by @nonamethanks.

create alias ginkgo -> ginkgo_tree

this tag is for the tree, but sounds ambiguous enough to be used for ginkgo leaf too. same format as the other *_tree tags, but if someone prefers it another way let me know.

Question: Should ginkgo leaf be tagged on ginkgo tree posts? Then we might as well implicate them. Currently 2/5 of ginkgo are tagged ginkgo leaf and 3/5 are not.

that would be like tagging leaf on tree (which funnily enough, there are 10k posts of) and I don't think that's worth it. only if both the tree/its branch(es) and detached leaves are in the same image should both tags be used imo, like post #5835874 or post #5867733.

create alias gingko_leaf -> ginkgo_leaf
create alias gingko_tree -> ginkgo_tree
create alias gingko_nut -> ginkgo_nut
create alias gingko_print -> ginkgo_print

Both forms of the spelling are correct, however on Danbooru we use the kg spelling. This prevents duplicate tags.

BTW this BUR was the result of me googling "Chinese yellow leaf" since I forgot what it was then clicking on and being bamboozled by the first image result that used the gk spelling.
