[SethuSenthil]

This pull request introduces the thread-year-prog-bot project, an open-source project that showcases the implementation of a practical Instagram Threads bot using the threads-API. The project serves as both an educational resource and a reference for developers interested in building similar applications and to also have an existential crisis!

Additionally, this pull request includes an automatic formatting update to the .imgbotconfig file.

Changes:

• Added thread-year-prog-bot project, demonstrating a real-world Instagram Threads bot example using the threads-API.
• Auto-formatted the .imgbotconfig file for improved code consistency.
