pygbag: add page

Add tldr page for pygbag - a tool for packaging Pygame games as WebAssembly.

pygbag allows Python/Pygame games to run directly in web browsers without
requiring users to install anything. It compiles projects to WebAssembly
and includes a built-in test server for local testing.

Closes tldr-pages#17002
