Update result for when curly braces are present

[UmairJibran]

Hey, I recently copied my PGN from chess.com to be analyzed on @WintrCat's Freechess but the PGN kept failing parsing, upon further investigation, I found that the result in the .peg file did not handle the curly braces case, hopefully this would resolve that.

Here's the PGN for the said game.
