[PRQ#50188] Deletion Request for java-activation-gnu

MarsSeed [1] filed a deletion request for java-activation-gnu [2]: Cleanup after the deletion of the broken, unused opengts (PRQ#50186). java-activation-gnu was dropped from repo to AUR in May 2021, and seems to have been abandoned ever since. Its upstream is no longer maintained: CVS repo deleted. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/java-activation-gnu/
