[PRQ#58628] Deletion Request for qgnomeplatform-git

MarsSeed [1] filed a deletion request for qgnomeplatform-git [2]: EOL since Aug 2023 [a], continues to fail to build for the last 6 months. I think it is safe to delete at this point. Has no reverse dependencies. Upstream's successor project is qadwaitadecorations, supporting both Qt5 & Qt6. Available on AUR.
