Report the `note` when specified in `diagnostic::on_unimplemented` #130123

FedericoBruzzone · 2024-09-08T23:37:21Z

Before this PR the note field was completely ignored for some reason, now it is shown (I think) correctly during the hir typechecking phase.

Report the note when specified in diagnostic::on_unimplemented
Added a test for unimplemented trait diagnostic
Added a test for custom unimplemented trait diagnostic

Close #130084

P.S. This is my first PR to rustc.
