TriggerCustomResourceProvider takes only the status code of Invoke API call into account.

const invokeResponse = await invoke(handlerArn, invocationType, parsedTimeout);
if (invokeResponse.StatusCode && invokeResponse.StatusCode >= 400) {
throw new Error(`Trigger handler failed with status code ${invokeResponse.StatusCode}`);
}

If invocationType is EVENT, Lambda function is invoked asynchronously. In that case, if Lambda function is invoked successfully, the trigger will success regardless of the result for the function execution. I add this consideration into README.

Closes #26341
