input: Write a function to schedule a job to run every day at a specific time using the 'schedule' library.
  assert schedule_daily_job("10:00") == "Job scheduled to run every day at 10:00"
  assert schedule_daily_job("08:00") == "Job scheduled to run every day at 08:00"
  assert schedule_daily_job("23:59") == "Job scheduled to run every day at 23:59"
output: import schedule
  import time
  
  def schedule_daily_job(time_str):
      def job():
          print("Job is running")
  
      schedule.every().day.at(time_str).do(job)
      
      return f"Job scheduled to run every day at {time_str}"
  
  # To actually run the scheduled jobs, you would need to call schedule.run_pending() in a loop
  # while True:
  #     schedule.run_pending()
  #     time.sleep(1)
