[PRQ#67233] Merge Request for raiderio-client-appimage

MarsSeed [1] filed a request to merge raiderio-client-appimage [2] into raiderio-client [3]: Please kindly eliminate duplication. Upstream is closed-source, both packages are from same maintainer and both are based on upstream's AppImage release. In such a case, a pkgname suffix like'-bin' or '-appimage' is superfluous.
