Updated the 2D examples to make them uniform (#17237)
# Objective

Make the examples look more uniform and more polished.
following the issue #17167

## Solution

- [x] Added a minimal UI explaining how to interact with the examples
only when needed.
- [x] Used the same notation for interactions ex : "Up Arrow: Move
Forward \nLeft / Right Arrow: Turn"
- [x] Set the color to
[GRAY](https://github.com/bevyengine/bevy/pull/17237#discussion_r1907560092)
when it's not visible enough
- [x] Changed some colors to be easy on the eyes
- [x] removed the //camera comment
- [x] Unified the use of capital letters in the examples.
- [x] Simplified the mesh2d_arc offset calculations.
