Lets add french language.

• Create new file translation.php in the fr folder in the resources/lang folder and add the below code.

  <?php
                  // translation.php
                  return [
                          'welcome' => 'Welcome Friend'
                  ];
              

• You need to add the new language option in the topbar resources/views/layouts/topbar.blade.php. Make sure to add it flag image and option in the dropdown.
