Schedule Cron Event

• The code includes functions to schedule and run the cron job responsible for executing tasks at specified intervals.
• The schedule_feed_cron_job() function schedules the cron job based on the selected recurrence option and feed status.
• The run_feed_cron_job() function defines the tasks to be performed when the cron job is triggered, such as displaying an admin notice.
