Remove unnecessary --workspace flags in CI commands.

The top-level `Cargo.toml` specifies a virtual workspace (one
without a `[package]` section). This means the `--workspace` flag is
unnecessary, because Cargo commands will process all crates by default.
See
https://doc.rust-lang.org/cargo/reference/workspaces.html#virtual-workspace.
