Let's add the French language.

• Create a new file fr.json in the fr folder in the src/app/locales folder. Import that file into src/app/locales/index.ts file.
• Now update the below code in the src/app/locales/flags.ts file. Add below code in flagByLanguage.
  { flag: frFlag // add svg file in flags folder and then import it here, language: "fr", title: "French", }
• To change default language to french? update below code in the src/plugins/i18n.ts file
  createI18n({ ... const locale: string = process.env.VUE_APP_I18N_LOCALE || "fr"; const fallbackLocale: string = process.env.VUE_APP_I18N_FALLBACK_LOCALE || "fr"; ... })
