The bulk update request #11488 has been approved by @evazion.
create alias kusanali_(genshin_impact) -> nahida_(genshin_impact)
The name used in her official reveal, described as a "Mysterious Girl". If at some point a distinction is needed like with Venti/Barbatos and Zhongli/Rex Lapis, then it can be unaliased.
For now it's better to alias than to rename since it's the name most people use for her.
