accounts/abi/bind: fix gas price suggestion with pre EIP-1559 clients (#23102) 

This fixes transaction sending in the case where an app using go-ethereum v1.10.4
is talking to a pre-EIP-1559 RPC node. In this case, the eth_maxPriorityFeePerGas
endpoint is not available and we can only rely on eth_gasPrice.
