[PRQ#52507] Deletion Request for mate-terminal-gtk2

MarsSeed [1] filed a deletion request for mate-terminal-gtk2 [2]: Broken Gtk2 based Mate component from 2017. Mixes Gtk2 and Gtk3 based libraries. Not useful to keep. MATE is Gtk3 based since 2017. Repo carries the latest mate-terminal. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/mate-terminal-gtk2/
