docs(changelog): Change wording about auto-fix message

The wording in the changelog regarding the auto-fix message specified that it would show for "warnings/errors", but Cargo only shows the message for warnings currently.

The reason that errors were not included was that there were concerns with `rustfix`/`cargo`'s ability to deal with errors, so we decided to skip showing it when there were any errors.
