Enhanced the design of the 'invite-user' and 'confirm-email' templates by adding new CSS code. This CSS code professionaly styles the email, improving readability and user experience.
The email-templates package now uses the i18n (internationalization) library to translate email content based on user language preferences. This update involves changes to the email structure, the addition of translation JSON files, and modifications to the files referencing the emails. Email file locations were also restructured for better organization.
