[aur-requests] [PRQ#35992] Deletion Request for ruby-fetcher

MarsSeed [1] filed a deletion request for ruby-fetcher [2]: Deprecated since 2015. Nothing depends on it on AUR; only abandoned modules use it on RubyGems. So I suggest to drop this package. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/ruby-fetcher/
