[nsipplswezey]

After syncing with latest changes on main branch CI fails on my fork on cargo_docs with linting errors:

Some research highlighted that this linting was added in 1.73
rust-lang/rust#113167
rust-lang/rust#87799

Confirmed same linting errors on my local up-to-date main branch as well.
