Add kanban pizza game

I'd like to suggest adding Kanban Pizza to your resources list.

It's an interactive online game that brings Agile and Kanban principles to life through a fun, pizza-making simulation. The game is inspired by agile42's classic Kanban Pizza Game and is open source - https://github.com/adamclement-exe/kanbanpizza.

I believe it’s a great tool for teams looking to practice Agile in a playful, engaging way. Thanks for considering its addition!
