Add SuparMario Sis Adventure (Platformer Game)

[m3hrab]

Add SuparMario Sis Adventure to the Platformers list.

• Repo: https://github.com/m3hrab/SuperMario-Sis
• Short: A 2D platformer built with Python and Pygame with enemy AI, modular JSON levels and a custom level editor.

I confirmed the game is not already on the list and placed the entry in lexicographic order (between Sonic Robo Blast 2 and Super Mario 64). Thanks!
