Invalid test data on TestGetValidMovesBlackBishop

[ghost]

The expected test values for this test duplicate values along the same axis, and do not have the appropriate values on the second direction of the bishop's moves.

Should be more like this:

List<Move> expected = new List<Move>()
            {
                new Move("D4", "A1", Player.Black),
                new Move("D4", "B2", Player.Black),
                new Move("D4", "C3", Player.Black),
                new Move("D4", "E5", Player.Black),
                new Move("D4", "F6", Player.Black),
                new Move("D4", "G7", Player.Black),
                new Move("D4", "H8", Player.Black),
                new Move("D4", "C5", Player.Black),
                new Move("D4", "B6", Player.Black), 
                new Move("D4", "A7", Player.Black), 
                new Move("D4", "E3", Player.Black), 
                new Move("D4", "F2", Player.Black), 
                new Move("D4", "G1", Player.Black)
            };

I have a bunch of changes on my fork, so I'm not feeling like submitting a pr to fix this, but just figured I'd let you know. 😸
