Rollup merge of #45574 - nzig:on_unimplemented_example, r=steveklabnik
Fixed rustc_on_unimplemented example in Unstable Book I saw [this](https://doc.rust-lang.org/beta/unstable-book/language-features/on-unimplemented.html) example and it seemed wrong. This fixes the example to emit an error message that makes more sense.
