Fix the name of Kiriyama An in Mono

BUR #42237 has been approved by @nonamethanks.

rename kiriyama_ann -> kiriyama_an

On second thought, "Kiriyama Ann" is neither the official spelling nor the default Hepburn romanization of 霧山アン, so the tag kiriyama_ann shouldn't be aliased anyway. It seems like a name produced by machine translation, likely because the given name is written in katakana. To illustrate this, consider how 志摩リン might be rendered as "Shima Lynn" instead of the more accurate "Shima Rin" in the same manner.
