1. Clone the asdf-vm repo
2. Use default settings or explicit set always_keep_download to no in asdfrc
3. Add a plugin that doesn't support keep_downloads, for example deno
4. Try to install any version of deno runtime

It's checking if keep_downloadis not equal to truenor yes and tries to remove the directory, however if the directory does not exist it shows the warning, the warning should be behind a check to see if the option is set
