Izumi Yuuki copyright qualifier

BUR #29977 has been approved by @nonamethanks.

rename izumi_yuuki -> izumi_yuuki_(yubinetsu)

Adding the copyright qualifier to not confuse the character with another Izumi Yuu, whose given name is revealed to be Yuuki.

Maybe (yubinetsu) would be a better qualifier here, otherwise it gets too long.
