[aur-requests] [PRQ#19026] Deletion Request for heroku-toolbelt

WhyNotHugo [1] filed a deletion request for heroku-toolbelt [2]: This application has been deprecated upstream for years now. We've had heroku-cli in the AUR since then too. No need to keep this around. [1] https://aur.archlinux.org/account/WhyNotHugo/ [2] https://aur.archlinux.org/pkgbase/heroku-toolbelt/
