Update code to match rust-lang changes to rustdoc type/field names

[Billy99]

With recent rust nightly build (nightly-2024-09-10), rust-lang, via PR130133 pulled in PR128667. This change a lot of type and field names. Now, the crate https://github.com/cargo-public-api/cargo-public-api, which depends on this project, is failing with missing field errors.
