fix(ci): restrict arm64 bundles to deb,rpm — skip AppImage

linuxdeploy-aarch64.AppImage cannot be reliably executed in a cross-
compile context (amd64 host, aarch64 target) even with QEMU binfmt
and APPIMAGE_EXTRACT_AND_RUN. The .deb and .rpm cover all major arm64
Linux distros. An arm64 AppImage can be added later via a native
arm64 build job if required.
