Summary of Changes
This PR fixes an issue where the alias does not reset properly when saving an article as a copy in the Joomla front-end. Previously, Joomla would append a # to the old alias instead of generating a new one based on the new title.

Changes made:

Updated the save method to reset the alias when saving an article as a copy.
Ensured that Joomla regenerates the alias correctly based on the new title.
Testing Instructions
Login to the Joomla front-end.
Find an article and click Save as Copy.
