[refactor]: remove hacks used to spoof SoD specific dungeon info

[juemrami]

• As of 1.15.5 blizzard has added these SoD dungeons onto the GroupFinderActivity.db2 table.
• Stub for the future raid "Nightmare Grove" left commented out for now
• Eventually, WB key should be dissolved into AZGS and KAZK as well
  • can then treat them like Scarlet Monestary or Dire Maul and have all world bosses be group-able into a single category.
