update info on Dexscreener and Dextools

[hackfisher]

We need to update all info on Dexscreener and Dextools. On Polkadot Omni Pool, $RING isn’t listed under Polkadot on Dexscreener—an - Isolated Pool or API integration may be required, which needs advocacy from the Hydration team. Also, add $KTON for trading on Arbitrum and/or Polkadot. The community should actively tag $RING and $KTON, including contract addresses, to boost visibility. Launching a Pump token launchpad could drive speculation and attract interested parties.
