fix(service-error-classification): treat Node.js network errors as transient

[trivikr]

Issue #, if available:
Internal JS-5916

Description of changes:
Treat Node.js network errors as transient

Verified in local testing by disabling WiFi that 3 attempts are made

Test code

import { STS } from "@aws-sdk/client-sts";
new STS().getCallerIdentity();

Before

$ node:internal/process/promises:394
    triggerUncaughtException(err, true /* fromPromise */);
    ^

Error: getaddrinfo ENOTFOUND sts.us-west-2.amazonaws.com
    at GetAddrInfoReqWrap.onlookupall [as oncomplete] (node:dns:122:26) {
  errno: -3008,
  code: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'sts.us-west-2.amazonaws.com',
  '$metadata': { attempts: 1, totalRetryDelay: 0 }
}

Node.js v22.15.1

After

$ grep NODEJS_NETWORK_ERROR_CODES node_modules/@smithy/service-error-classification/dist-cjs/index.js

var NODEJS_NETWORK_ERROR_CODES = ["ENOTFOUND"];
var isTransientError = /* @__PURE__ */ __name((error, depth = 0) => isClockSkewCorrectedError(error) || TRANSIENT_ERROR_CODES.includes(error.name) || NODEJS_TIMEOUT_ERROR_CODES.includes(error?.code || "") || NODEJS_NETWORK_ERROR_CODES.includes(error?.code || "") || TRANSIENT_ERROR_STATUS_CODES.includes(error.$metadata?.httpStatusCode || 0) || isBrowserNetworkError(error) || error.cause !== void 0 && depth <= 10 && isTransientError(error.cause, depth + 1), "isTransientError");

$ node test.mjs
node:internal/process/promises:394
    triggerUncaughtException(err, true /* fromPromise */);
    ^

Error: getaddrinfo ENOTFOUND sts.us-west-2.amazonaws.com
    at GetAddrInfoReqWrap.onlookupall [as oncomplete] (node:dns:122:26) {
  errno: -3008,
  code: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'sts.us-west-2.amazonaws.com',
  '$metadata': { attempts: 3, totalRetryDelay: 226 }
}

Node.js v22.15.1
