create alias y_(pokemon), yvonne_(pokemon), yvonne_gabena -> y_na_gaabena

BUR #2366 has been approved by @evazion.

create alias y_(pokemon) -> y_na_gaabena
create alias yvonne_(pokemon) -> y_na_gaabena
create alias yvonne_gabena -> y_na_gaabena

Reason:

• The current tag is just y_na_gaabena (her full name in Japanese).
• y_(pokemon) and yvonne_(pokemon) would be simple names like 99%+ human characters from Pokémon media. Compare the existing aliases green_(pokemon) (aliased to ookido_green) and platinum_(pokemon) (aliased to platinum_berlitz).
• yvonne_gabena is her official English name.
