Feature request: append dial code to phone number based on the country code

[kkyusuftk]

Feature Summary

add the dial code to the number based on the country code
appendCountryCode('9876543210', 'IN') --> +919876543210
appendCountryCode('3232666451', 'US') --> +13232666451

Use Case

There was a use case where we were getting a phone number and the country code (US, IN). We wanted to add the dial code to the number based on the country code.
Seems like a good feature to add to this library.
You folks already have the mapper in place https://github.com/razorpay/i18nify/blob/master/packages/i18nify-js/src/modules/phoneNumber/data/dialCodeMapper.ts
