temporarily pin clap and anstyle dependencies (#190)

This commit temporarily pins the clap dependency version to v4.3.24, since v4.4 changed Clap's MSRV to Rust 1.70, which our dev image doesn't have yet. It was also necessary to add an explicit dep on anstyle, a transitive dep via clap, so that we could pin that crate to v1.0.0, as v1.0.1 of anstyle also requires Rust 1.70
