create alias aegis_(persona) -> aigis_(persona)

It's spelled Aigis in English. https://megamitensei.fandom.com/wiki/Aigis

Normally I'm for keeping the Japanese name as the main tag, but this is just the same name spelled differently. I've also only ever seen the fandom call her Aigis.

I did a little research. Apparently the name change was done to maintain the Japanese pronunciation. Otherwise the English pronunciation would've been "ee-juhs" instead of "EYE-gus".

Just a bit of trivia on the topic.
