Add cargo-semver-checks to linting category (#105)

`cargo-semver-checks` is used by many large projects in the Rust ecosystem, such as `tokio` and even `cargo` itself. Add it as a recommendation in the linting category.

If you feel a different category would be a better fit, I'd be happy to move it there.

Thanks for maintaining this list!
