Finish button & functionality added

[SURAJ-SHARMA27]

Description

This feature PR adds a finish button to the tutorial publishing page. When a user publishes their tutorial, the finish button will be enabled and allow them to redirect to the homepage. If the tutorial is unpublished, the finish button will be disabled. This change was made to improve the user experience by allowing users to easily redirect to the homepage after publishing their tutorial. Previously, there was no way to do this without using the browser's back button.

Motivation and Context

Users need to be able to easily redirect to the homepage after publishing their tutorial so that they can continue using the application.
