Follow routes

[Dhooly]

Description / Changes Made

• Added a new Flask blueprint named follow_bp to handle user follow/unfollow operations.
• Implemented routes (/api/users//follow/ and /api/users//unfollow/) within follow_bp to follow and unfollow users, respectively.
• Included error handling to check for user existence before performing follow/unfollow actions.
• Ensured JSON responses with appropriate HTTP status codes are returned based on success or failure scenarios.
• Added docstrings explaining the purpose, arguments, and behavior of the follow_user and unfollow_user functions.

Portions of this code that utilized AI generation

I utilized Github's copilot for inline code generation for some of the boilerplate and if statements for the routes I created.
