This fixes an issue that was introduced when the icon was updated for Big Sur.
The update assumed that the icon should always be white, but actually both black and white icons should be provided so that the operating system can choose what's most appropriate.
You can see in the bellow video by changing my desktop background colour I can get the icon to toggle between black and white.
