USN-8287-2: XDG Desktop Portal regression

USN-8287-1 fixed a vulnerability in XDG Desktop Portal. Unfortunately the fix for CVE-2026-40354 was incomplete and introduced a regression when trashing files. This update fixes the problem and provides the corresponding update for Ubuntu 26.04 LTS. We apologize for the inconvenience. Original advisory details: It was discovered that XDG Desktop Portal incorrectly handled trashing files. A local attacker could possibly use this issue to delete arbitrary files on the host file system via a symlink attack.
