fix: Correct use of supertrait_item_shadowing lints

These were recently renamed, and are also apparently unstable. I'm not
sure how I keep failing to realize I'm using unstable lints. If I'm not
mistaken, these are just about to stabilize in [rust-lang/rust!148605].
As in, the PR is currently in disposition merge.

[rust-lang/rust!148605]: rust-lang/rust#148605
