Update to the Nameless One & Redstone Monstrosity

The Nameless One and the Redstone Monstrosity need to be updated. Recently in the seasons for Minecraft Dungeons, a lot of DLC bosses have been getting updates. The Jungle Abomination got poison to the melee attack, a poison darts attack, and a smaller arena. The Wretched Wraith got invulnerability during its flurry attack, a new variation to its flurry attack, and more mob summons. The Tempest Golem got invulnerability until it is stunned. With these updates, the Nameless One and Redstone Monstrosity need updates as well. The DLC bosses have at least two more attacks than the Nameless One and Redstone Monstrosity so if updated they need more attacks.
