Rollup merge of #83392 - ehuss:w-help-edition, r=varkor

Change `-W help` to display edition level.

`-W help` was not honoring the `--edition` flag when displaying the default lint level. It was using the edition for sorting, but not for the final display.

This isn't important right now as there aren't any edition-specific lint levels. Also, the `declare_lint` macro is broken and doesn't even allow setting them right now. However, I figure it wouldn't hurt to fix this before I forget about it, in case edition-specific lints are ever used in the future.
