Add tests to validate L1BlockInfo in RPC receipts for Optimism hardforks

[Wodann]

Currently, we only have one test validating L1BlockInfo for a remote transaction in crates/edr_optimism/tests/rpc.rs:

#[tokio::test(flavor = "multi_thread")]
async fn receipt_with_l1_block_info() -> anyhow::Result<()> {
    const TRANSACTION_HASH: B256 =
        b256!("f0b04a1c6f61b2818ac2c62ed0c3fc22cd7ebd2f51161759714f75dd27fa7caa");

    let url = get_alchemy_url().replace("eth-", "opt-");
    let rpc_client = EthRpcClient::<OptimismChainSpec>::new(&url, CACHE_DIR.into(), None)?;

    let receipt = rpc_client
        .get_transaction_receipt(TRANSACTION_HASH)
        .await?
        .expect("Receipt must exist");

    assert_eq!(receipt.l1_block_info.l1_gas_price, Some(0x5f3a77dd6));
    assert_eq!(receipt.l1_block_info.l1_gas_used, Some(0x640));
    assert_eq!(receipt.l1_block_info.l1_fee, Some(0x1c3441e5e02));
    assert_eq!(receipt.l1_block_info.l1_fee_scalar, None);
    assert_eq!(receipt.l1_block_info.l1_base_fee_scalar, Some(0x146b));
    assert_eq!(receipt.l1_block_info.l1_blob_base_fee, Some(0x3f5694c1f));
    assert_eq!(receipt.l1_block_info.l1_blob_base_fee_scalar, Some(0xf79c5));

    Ok(())
}

We should add more tests to validate:

• One test per supported Optimism-specific hardfork for remote RPC receipts
• One test per supported Optimism-specific hardfork for locally mined RPC receipts

A list of Optimism-specific hardforks can be found here.

Hi @Wodann I want to contribute to this, but can you give me more information? I'm not entirely clear on what needs to be done for this issue.

[Wodann]

I've added more information to the issue description that should provide you with a starting point to investigate the issue.

1. I have check this, the optimism has six hardforks, so i need find the transaction hash after the hardfork block number, then write tests for the remote RPC receipts.(similar to receipt_with_l1_block_info function)

2. What is locally mined RPC receipts ?
