test(verify_pdf): skip the symlink refusal check where symlinks need a privilege

On Windows, Path.symlink_to raises WinError 1314 for a user without
Developer Mode or admin rights, which turned the test into an error on a
developer machine. GitHub's Windows runners create symlinks fine, so CI
still exercises it; elsewhere the test now skips with the reason.
