Add qualifier to Castle in the Sky's Dola tag

BUR #17880 has been approved by @nonamethanks.

rename dola -> dola_(laputa)

Now that there's a Nijisanji vtuber named Dola, the tag of Dola from Tenkuu no Shiro Laputa should receive its own alias to disambiguate the two.

All the other characters with a qualifier use "_(laputa)", not the full name.

Alright, thanks for heads-up.
