Use standard instruction text / position in various examples (#13583)

## Objective

Use the "standard" text size / placement for the new text in these
examples.

Continuation of an effort started here:
https://github.com/bevyengine/bevy/pull/8478

This is definitely not comprehensive. I did the ones that were easy to
find and relatively straightforward updates. I meant to just do
`3d_shapes` and `2d_shapes`, but one thing lead to another.

## Solution

Use `font_size: 20.0`, the default (built-in) font, `Color::WHITE`
(default), and `Val::Px(12.)` from the edges of the screen.

There are a few little drive-by cleanups of defaults not being used,
etc.

## Testing

Ran the changed examples, verified that they still look reasonable.
