[PRQ#57446] Deletion Request for rapidsvn

MarsSeed [1] filed a deletion request for rapidsvn [2]: Build is broken; reported as such since 2021-08-31. Last stable releases used here is from 2012, and upstream's GitHub repo has been abandoned for 3 years. [a] Even the last master branch code is unbuildable on current Arch Linux. Seems best to delete this dead package. [a]: https://github.com/RapidSVN/RapidSVN [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/rapidsvn/
