Publish as Plasma 6 on the KDE Store (Pling)

This KWin script has already been ported to Plasma 6 (see #3 (closed)). However, its listing is still tied to Plasma 5, and thus it doesn't show up in the "Get New…" dialog from the KWin Scripts section of System Settings.

Look:

• https://store.kde.org/p/1833846 → Shows as KWin (Plasma 5) as the category. I can't install it.
• https://store.kde.org/p/1702170 → Is available for download.
