feat: Print centered pyramid star pattern using nested loops

🧠 Logic:
- Accept user input `n` for the number of pyramid levels.
- Outer loop (`i`) runs from 1 to `n` for each row.
- First inner loop prints `n - i` spaces to center the stars.
- Second inner loop prints `2 * i - 1` stars to form the pyramid shape.
- A newline is printed after each row to maintain pyramid structure.

 To determine the number of spaces and stars in each row, follow these steps:
 
 Spaces:

 For each row i, the number of spaces decreases as i increases.
