clippy: Configure via `lints` table in `Cargo.toml` (#185)

As of Rust 1.74, lints can be configured within the `Cargo.toml`
which allows us to not have to configure them in the source code
as well as simplifying having a single configuration across an
entire workspace.

This is documented at: https://doc.rust-lang.org/nightly/cargo/reference/manifest.html#the-lints-section
