don't copy `.rustc-dev-contents` from CI rustc Since https://github.com/rust-lang/rust/pull/127188, copying files from `.rustc-dev-contents` regressed https://github.com/rust-lang/rust/issues/108767 again. Since `rustc-src` is already included in the CI rustc sysroot, we don't need to copy these files to have `rustc-src` component. Blocker for #122709
