Rename Seishou_Music_Academy_uniform

BUR #19605 has been rejected.

create alias seishou_music_academy_uniform -> seishou_music_academy_school_uniform
remove alias seishou_music_academy_uniform -> seishou_music_academy_school_uniform

A series-specific school uniform, the Wiki says so.
Changed into a rename for consistency and automatic implication.

I thought what we did in cases like this was to end the tag with _school_uniform, even if it's redundant, so the auto-implication takes effect.

There are a bunch of Assault Lily uniform tags set up like that: herensuge girls academy school uniform, ludvico private girls' academy school uniform, yurigaoka girls academy school uniform.

Should those tag names be changed and then implied to school_uniform? (Though now that I check, several of them need apostrophes added anyway.)
