Moved Whisky from Mac Apps to Mac Gaming and starred for better relevancy

[ThomsenDrake]

Description

• Moved the Whisky app from Mac Apps to Mac gaming as it's more relevant there.
• Starred Whisky app as it's the easiest implementation of the Apple Game Porting Toolkit and WINE for non-technical users and is free unlike Crossover

Context

• While Whisky is technically part of the Mac Apps category, it fits much better in the Mac Gaming category, as it's an app that specifically helps Mac users play games designed for Windows
• Whisky's installer automatically installs and configures Apple's Game Porting Toolkit and WINE. In addition, it's also a much more friendly UI than other implementations
