[PRQ#46748] Deletion Request for vala0.52

MarsSeed [1] filed a deletion request for vala0.52 [2]: This legacy version was uploaded in 2021 specifically for one AUR package: https://aur.archlinux.org/packages/dee But since 2022, the latter has been patched so it no longer needs this older vala. Therefore I recommend deleting this. Nothing depends on it on AUR now. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/vala0.52/
