Random Number Selection from Generated String

This function first checks if the specified directory exists, and if not, creates it. Then, it writes a randomly generated string to a file in the directory. Next, the function reads the file content, converts it to JSON format, and uses regular expressions to find all the numbers. Finally, it randomly selects one of these numbers and returns it.
