Update default ClearColor to better match Bevy's branding (#10339)
# Objective

- Changes the default clear color to match the code block color on
Bevy's website.

## Solution

- Changed the clear color, updated text in examples to ensure adequate
contrast. Inconsistent usage of white text color set to use the default
color instead, which is already white.
- Additionally, updated the `3d_scene` example to make it look a bit
better, and use bevy's branding colors.
