[PRQ#61973] Deletion Request for etesync-git

MarsSeed [1] filed a deletion request for etesync-git [2]: Etesync development has been abandoned since 4 years ago [a] in favor of its refactored, renamed successor, etebase. [b] This AUR package fails to build as of now. It does not seem useful to keep the developmental git package for the discontinued legacy version. [a]: https://github.com/etesync/etebase-rs/tree/legacy [b]: https://github.com/etesync/etebase-rs [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/etesync-git/
