--without=rust-docs breaks installs with Rust 1.66.0.0

[zRedShift]

Bug description

Upstream rust added the rust-docs-json-preview component, so this breaks the --without command since it performs rudimentary string replacement and it turns rustc, rust-std-x86_64-unknown-linux-gnu, rust-docs, rust-docs-json-preview, cargo into rustc, rust-std-x86_64-unknown-linux-gnu, -json-preview, cargo, with -json-preview of course being non-existent.
