RFR: 8329703: Remove unused apple.jpeg file from SwingSet2 demo

[Mikael Vidstedt]

The following two files have the exact same contents:

src/demo/share/jfc/SwingSet2/resources/images/food/apple.jpg
src/demo/share/jfc/SwingSet2/resources/images/food/apple.jpeg

Only the first one is actually used in the demo. The latter is unused and should be deleted.

Testing: tier1 + verified that Robi Khan still has a beautiful looking apple as their favorite food in the demo
