Move to trash functionality fixed

[SURAJ-SHARMA27]

Description

Made necessary changes ensuring that both functionalities now work correctly. Specifically, users cannot delete a tutorial before unpublishing it. After unpublishing, the "Move to Trash" button becomes enabled, and upon clicking it, the tutorial is successfully deleted from the database. Additionally, I removed the extra finish modal as per the feedback.
