Description
ethers_core::types::BlockNumber doesn't implement Serialize and Deserialize traits.

I tried this code:

fn main() {
    let block_number = BlockNumber::Number(42.into());
    let serialized = serde_json::to_string(&block_number).unwrap();
    println!("Serialized BlockNumber: {}", serialized);

    let latest_block_number = BlockNumber::Latest;
    let serialized_latest = serde_json::to_string(&latest_block_number).unwrap();
    println!("Serialized Latest BlockNumber: {}", serialized_latest);
}

I expected to see this happen:
It should serialize BlockNumber.

Instead, this happened:
BlockNumber is not serialized.
