don't copy .rustc-dev-contents from CI rustc

onur-ozkan · onur-ozkan · commit fa6d54f5c437 · 2024-08-20T16:13:59.000+03:00
Since #127188, copying files from `.rustc-dev-contents` regressed #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. Signed-off-by: onur-ozkan <work@onurozkan.dev>
