This update adds support for Indian national and festival holidays in the HR system, including Makar Sankranti, Republic Day, Independence Day, and Gandhi Jayanti. The holidays are now automatically configured when the Indian localization module is installed, making it easier for Indian companies to manage employee time off and holiday schedules.

In this commit we remove the Public holidays from `data` and add it using post_init_hook.
​ India Festival and National Holidays:
  - Makar Sankranti - January 14th
  - Republic Day - January 26th
  - Independence Day - August 15th
  - Gandhi Jayanti - October 2nd
