Announcement: Full Wayland support for Desktop

[tsujan]

Although pcmanfm-qt works without problem under Wayland, its desktop module needed layer-shell-qt6 for working independently of probable workarounds provided by some Wayland compositors (like LabWC).

Now that layer-shell-qt6 has come to Arch, I've prepared a patch that makes pcmanfm-qt's desktop completely ready for Wayland. I'll make a PR soon after #1726 is merged.

Of course, pcmanfm-qt will work under X11 indefinitely.
