Changed the preview thumbnail to remove the captions on the bottom left.

It originally just detailed some of the stage quirks, specifically:
"* Player-Focused Camera"
"* Spectator Cam in FFA"
"* Custom Victory"
"* this isn't a simple stage port dont dismiss it just yet ;-;"

realized i was being way too conscious of what others might think and decided to discard that part since it isn't very healthy.
