Blyssade as artist, not generic tag

BUR #8817 has been approved by @evazion.

category blyssade -> artist

Mistagged blyssade to generic tag rather than artist during upload of #5107043, not sure how to fix this as it's my first time uploading.

Changed it manually.

@miritsu For future reference, you should use https://danbooru.donmai.us/artists/new to create a new artist tag before you add it to an upload. The upload page will have a "Create a new artist" link that you should use if there's no artist entry for that artist yet.

You can also just use "artist:tagname" or "art:tagname"; a banner should appear automatically after you submit it to prompt you to create the artist entry. Doing it this way will also automatically populate the urls and name for you if you're doing this from a post with a supported source.
