Fixed typo in toki pona text

New features since last release:
  - Display score breakdown, high score, and letter grades.
  - Options menu with volume control, keybindings, and true fullscreen.
  - Demos menu. View saved games!
  - Mouse controls, sorta. Mouse controlled menus!
  - High contrast mode.
  - Instructions displayed on startup.
  - Default demo ships with game.
  - Render sitelen pona quote symbols to and te
  - Beat combo indicator.

Outstanding defects:
  - Options menu not persistent.
  - Mouse controls feel like complete dogshit.
