`#[warn(unexpected_cfgs)]` on by default
Heads up, with the release of rust-lang/cargo#13913 (in nightly-2024-05-19), there is no longer any need to allow the lint to avoid a build.rs as done in this PR. Cargo has now gain the ability to declare
[lints.rust]
unexpected_cfgs = { level = "warn", check-cfg = ['cfg(trybuild)'] }
