feat: Add nested switch examples for employee details using traditional and enhanced syntax

🔍 Details:
- Implemented two versions demonstrating nested switch statements.
- `NestedSwitch`: Uses both traditional and enhanced switch formats to print employee name and department.
- `NestedSwitch2`: Adds user prompts, newline handling, and clearer output labeling for better UX.
- Handles nested switch logic for employee ID 3 with department-specific outputs (IT/Management).

🧠 Purpose:
- Practice and compare traditional vs. enhanced switch syntax (Java 14+).
- Illustrate structured decision-making with nested conditions.
