Update workflow to new actions (alternative) (#505)

Alternative to #503

Using `actions-rust-lang` instead of `actions-rs` for
setup. (nushell uses them for setup with integrated caching)

Remove build stage as this should also be covered by test.
clippy --all to see if this checks the examples as well.
