Fix pink colors in examples

[rparrett]

Objective

I was wondering why the lighting example was still looking quite different lately (specifically, the intensity of the green light on the cube) and noticed that we had one more color change I didn't catch before.

Prior to the bevy_color port, PINK was actually "deep pink" from the css4 spec.

palettes::css::PINK is now correctly a lighter pink color defined by the same spec.

// Bevy 0.13
pub const PINK: Color = Color::rgb(1.0, 0.08, 0.58);
// Bevy 0.14-dev
pub const PINK: Srgba = Srgba::new(1.0, 0.753, 0.796, 1.0);
pub const DEEP_PINK: Srgba = Srgba::new(1.0, 0.078, 0.576, 1.0);

Solution

Change usages of css::PINK to DEEP_PINK to restore the examples to their former colors.
