Merge #20941: rpc: document RPC_TRANSACTION_ALREADY_IN_CHAIN exception

Browse Source 
74d23bf7fb rpc: document RPC_TRANSACTION_ALREADY_IN_CHAIN exception (Jarol Rodriguez)

Pull request description:

  It is not documented in the `RPCHelpMan` of `sendrawtransaction` that if you attempt to send a transaction which already exists in a block, an `RPC_TRANSACTION_ALREADY_IN_CHAIN` exception will be raised. It is best to make developers aware of this so that it can be properly caught and avoid any headaches.

  Closes #5638
