Fixing theme toggle

[Jasleen1210]

The issue with the inversion of game images during light theme has been fixed. Only the game images are unaffected by the toggle and the font footer changes remain same as original. Also edited gamesData.json such that the games are in order and closed a bracket that was accidentally left open and causing error in the site.
