Tests rely on deprecated `assert_cmd::cargo_bin` which will break on future Cargo versions

Command::cargo_bin("css-inline").unwrap()

cargo_bin relies on implementation details of cargo that will soon break (rust-lang/cargo#16147, rust-lang/cargo#15010).

You can test this by running:

CARGO_BUILD_BUILD_DIR="{cargo-cache-home}/build/{workspace-path-hash}" cargo test

The replacement is assert_cmd::cargo_bin!
