Created Automated Emails to Mentors

[IamLRBA]

How It Works

• Help Description:
  The help attribute provides a short description of the command for reference.

• Fetch Project:
  Retrieves a project by its id using Project.objects.get(id=1).
  You can replace id=1 with dynamic logic (e.g., looping through all projects or filtering based on criteria).

• Retrieve Mentor Emails:
  Calls project.get_mentor_email_list() to get a list of mentor emails.
  Ensure this method is implemented in the Project model.

• Send Emails:
  Iterates through each email in mentor_emails.
  Composes a personalized message and sends it using send_mail.

• Console Feedback:
  Logs the success of each email using self.stdout.write.
  Provides confirmation once all emails have been sent.
