* chore: bump version to 2.23.9 and update dependencies
- Updated application version from 2.23.8 to 2.23.9 in package.json.
- Added @types/node dependency in email-templates package.json for improved type support.
- Introduced NEXT_PUBLIC_DEFAULT_LOCALE environment variable in web app for localization settings.
- Updated i18n initialization to utilize the new default locale setting.
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.
