[PRQ#49821] Deletion Request for mingw-w64-qt5-webkit

MarsSeed [1] filed a deletion request for mingw-w64-qt5-webkit [2]: Unused legacy package from 2017; upstream doesn't maintain it since 2020. Nothing depends on it on AUR, and also maintainer wrote in 2017 that they removed this build from their personally maintained binary repo due to not being needed anymore.
