feat: add TwoDimensionalArrays example demonstrating 2D array declaration and printing

Implemented TwoDimensionalArrays.java to show declaration, initialization,
and structured output of a 3x3 integer matrix without using loops.
Illustrates the basics of accessing and printing multi-dimensional arrays.
