Add functionality to add comments to tickets

A new controller, 'AddCommentController', has been added. This controller implements the 'AddCommentCommandHandler', allowing users to add comments to tickets. Additionally, corresponding test cases were implemented. The Ticket entity was also updated to accept and manage comments. API endpoint specs were updated to reflect these changes.
