Update cargo_toml to 0.22.3 and toml to 0.9

The code in `src/splicing.rs` uses `toml::Value` types that were
incompatible—the workspace used `toml` 0.8.x but cargo_toml 0.22.3 depends
on `toml` 0.9.x, creating a type mismatch. Therefore, `Cargo.toml` was
updated to use to use `toml = "0.9"` instead of `"0.8.21"`.
