Asynchronous Random URL Data Fetching with aiohttp

This function uses the aiohttp library to asynchronously fetch data from a random URL and prints it. It first defines an inner asynchronous function fetch_random_url, which randomly selects one from the predefined URL list and fetches its data. Then it defines an external function fetch_random_data, which starts an asynchronous event loop and calls the inner function.
