ci: tacd: use run: cargo deny instead of EmbarkStudios/cargo-deny-action

Other than the actions-rs actions the cargo-deny actionis actually
actively maintained, but replacing it with a simple `cargo deny` call
removes our last non-GitHub provided action dependency and makes it a bit
easier to determine what is actually happening in the action,
should one e.g. want to reproduce it locally.
