Fix Wikiless auto update workflow

Wikiless updated their instance json with a couple of changes that broke
Farside's auto update workflow:
- The protocol for each instance is now included by default (no need to prepend
  "https://")
- The instances are differentiated between regular, onion, and i2p (no need to
  check for ".onion" in regular instance URLs)
