script: support sending batches to optimism (foundry-rs#5134)

After bedrock, transactions are held in a mempool meaning that it
is possible to send batches of transactions. There is no need to
wait for each transaction to be confirmed before sending the next
like in the legacy system. This commit removes the need to send
transactions sequentially when using optimism with `forge script`
