refactor(examples): remove local example

[vados-cosmonic]

Feature or Problem

As we're about to replace the examples in wasmcloud/wasmcloud with component-first providers and actors (in various languages), we should probably remove the current example that's there which uses the local transport.

It's arguable that the local transport should be removed entirely, but that's out of scope for this change.

This commit removes the local example, which is almost identical to the tests/local.rs, in favor of the coming examples.

@connorsmith256 can you please re-run tests (and approve/re-merge since I needed to resolve conflicts and rebase + squash?)?
