Ignore user's curlrc during download (#771)

By using the `-q` flag, we avoid issues from existing `.curlrc` settings, especially the `-O` option that sends output to disk instead of stdout. Since we use curl more as a plumbing tool than an interactive user command , ignoring `.curlrc` ensures consistent behavior across setups.
