Disable Rust scanning in CodeQL workflow (#33) (#34)

The experimental Rust code in ARCHIVE/license-parser-experiments/ has no
Cargo.toml, causing CodeQL to report 0% call target and macro resolution
rates. Since this is archived experimental code without a proper Cargo
project, disable Rust scanning until a buildable Rust project is added
to the repository.
