This commit adds support for the German language variant 'de-DE' in the application. The following changes were made:
Created the '/public/locales/de-DE/common.json' file for the 'de-DE' language
Modified the 'SwitchLang.tsx' component to include the 'de-DE' language option
Updated the 'localeText' function to display ' Deutsch' for 'de-DE'
These changes enable the application to provide localization in German for the informal 'de-DE' language variant. The newly created '/public/locales/de-DE/common.json' file contains the necessary translations for the German language. The 'SwitchLang.tsx' component has been updated to include the German language option ('de-DE') with the appropriate flag and language name.
Users can now select the informal German language ('de-DE') to interact with the application.
