Create DungeonGame.java

[Tsurya06]

The DungeonGame class implements a solution to the Dungeon Game problem using dynamic programming. The goal is to determine the minimum initial health points needed for a knight to survive a dungeon represented by a 2D grid, where each cell contains a health value that can be positive or negative. The knight moves from the top-left corner to the bottom-right corner, and the solution calculates the minimum health required to ensure the knight's health never drops to zero or below at any point.
