[move-examples] Move to using _ placeholder notation in Move.toml

[gregnazario]

Description

The build system doesn't particularly like it when you provide an additional address for one that's hardcoded in the Move.toml. This changes to the placeholder notation.

Test Plan

CI should still pass if there's any automation that actually needed the fake addresses

I am curious "The build system doesn't particularly like it" in what way?

Compilation returns a weird error:
{ "Error": "Unexpected error: Unable to resolve packages for package 'test_packages'" }

We can't use this, looks like we need changes to the unit test framework. I'm closing this for now.
