Adding new Locale's

Using svelte-i18n Google Domains DDNS Updater now supports Locale selection on the UI (Default en-US)

Adding new locale's involves just a couple of steps.

1. First add the locale dictionary json files in web/public/lang/default/ and web/public/lang/friendly/ by copying the en.json and just changing the values of all keys
2. Second, the locale will need to be added to the locales list used by switcher component in web/config.js locales object
