PR Summary

• Updated Success Message in Profile
  The code has been tweaked in the 'ProfileController.php' file to modify the success message that users see. It now uses a different translation key, which will allow a smoother localization experience across various languages.

• Removed Line Breaks and Indentations in Language File
  There's been an optimization in the 'account/general.php' file where line breaks and indentations that were previously present in 'api_key_warning' and 'api_reference' have been removed. This creates cleaner lines of code and potentially less confusion when translated into different languages.
