fs: `copy` with `{ preserveTimestamps: true }` does not update the timestamps of symlinks

Deno doesn't have lutime API and the timestamp of symlink is not updated.

Can you please provide a minimal reproducible code snippet?

Set up files:

$ touch file.txt
$ ln -s file.txt link.txt

script:

import { copy } from "@std/fs";

copy("link.txt", "link-copy.txt", { preserveTimestamps: true });

$ deno run -A copy.ts
