Added Chain Param to Solana Notifications

We have released a fix for our Solana notifications, where they include the chain parameter.

Moving forward, you can expect the Solana notifications to include for:

Mainnet:"chain" : "solana-mainnet"
Testnet: "chain" : "solana-devnet"

Example Solana webhook with chain parameter:

{  
  "address": "CUAkqR6WKhvGaqf4hJYeUo2YhEsGL46RZGg7BFRJx6vP",  
  "type": "native",  
  "txId": "f1nZdcUnB2VRrmJ6u4wZN79APYdPxktQdEGj49fiR6LV6w4HA4puYyqQCYWWHvFLNLWos75KEqRi7yMZ8R6bohX",  
  "blockNumber": 303689174,  
  "asset": "SOL",  
  "amount": "-0.0001",  
  "subscriptionType": "ADDRESS_EVENT",  
  "chain": "solana-devnet"   //new parameter after the fix
}
