Aliasing agata_itsuki -> akata_itsuki.
Reason: I noticed that henmere added in a wiki note with the artist's comments on his name reading, and given that the family name should be "akata" instead. I was a little confused before, since I think I picked up the "agata_itsuki" reading at first looking around, but then post #220327 seems to suggest "akata_izki" or "akata_izuki". I guess the "izki/izuki" thing is just stylistic romanization (even if used for his own sites' URL's), since the artist himself says his given name is read いつき
