Random User Selection from Database

This function randomly selects a user from the database and returns the user's data. It first defines a metadata object, then reflects the 'users' table from the database, and then creates a select statement to select a random user from the 'users' table, limiting the results to one record. Finally, it executes the select statement and returns the user data.
