[Task (Dev-Tools)]: Cannot open wallet config file at "/.iota/iota_config/client.yaml". Err: missing field keystore

[Thoralf-M]

Bug description

iota client command failed to work, might be related to the yaml dependency update in #1106
Error is returned from here

iota/crates/iota-config/src/lib.rs

Line 91 in 7676306

Ok(serde_yaml::from_reader(reader)?)

Steps To reproduce the bug

1. Run iota client

Expected behaviour

Should work

Actual behaviour

Cannot open wallet config file at "/.iota/iota_config/client.yaml". Err: missing field keystore``

Not sure what happened, I even wrote a test that was failing for me
crates/iota/src/unit_tests/keytool_tests.rs

#[test]
async fn test_save_client_config() {
    let temp_dir = TempDir::new().unwrap();
    let client_config_path = temp_dir.path().join(iota_config::IOTA_CLIENT_CONFIG);
    let keystore_path = temp_dir.path().join(iota_config::IOTA_KEYSTORE_FILENAME);

    let keystore = FileBasedKeystore::new(&keystore_path).unwrap();
    keystore.save().unwrap();

    let keystore = FileBasedKeystore::new(&keystore_path).unwrap();
    let client_config = iota_sdk::iota_client_config::IotaClientConfig::new(keystore.into());

    use iota_config::Config;
    client_config.save(&client_config_path).unwrap();

    let _client_config: iota_sdk::iota_client_config::IotaClientConfig =
        iota_config::PersistedConfig::read(&client_config_path).unwrap();
}

but after checking out some other commits and going back it's working fine now with rustc 1.80.0 and 7676306 (also tried few commits before and they were also fine now)
