This update streamlines the demo data for the Indian payroll module (l10n_in_hr_payroll) by removing redundant working schedules. The change consolidates to a standard 40-hour work week, improving data consistency and reducing complexity. This ensures a more accurate and manageable demo environment.

### AIM

- In the demo data, there is no need to create multiple working schedules for Indian locations.
- We can use a single working schedule of 40 hours per week.
