Remove visiting links for handful of artists who are only commissioners

[towerofnix]

Review Tangle's remarks: #hsmusic-chat

• Keep artist entries (for future-oriented purpose of aliases/association-making, and because the pages themselves aren't at all harmful, containing only a name and nothing else)
• Remove URLs because "it would be pretty reasonable to only include Visible Artist Links if they are credited for something 'more substantial' than simply placing a commission: any artwork or music or flash credit basically"

These artists should be affected:

• https://hsmusic.wiki/artist/sonicbinch/
• https://hsmusic.wiki/artist/zerio/

Remaining commissioners either already don't have links:

• https://hsmusic.wiki/artist/sodiumcadaver/
• https://hsmusic.wiki/artist/zachary-torroni/

Or have "more substantial" contributions (and may already not have links):

• https://hsmusic.wiki/artist/animeseinfeld/
• https://hsmusic.wiki/artist/captain-moonstone/
• https://hsmusic.wiki/artist/chestnut/
• https://hsmusic.wiki/artist/feartehk/
• https://hsmusic.wiki/artist/glazelazer/
• https://hsmusic.wiki/artist/infiniteinconvenience/
• https://hsmusic.wiki/artist/ouhrin-siegru/
• https://hsmusic.wiki/artist/0verandoverandover/
• https://hsmusic.wiki/artist/shootdawhoop99/

Also, track Dunwich Lullabies is missing in-commentary link to artist 0verandoverandover.
