fix: add rpm to release-macos-aarch64.yml

[AdianKozlica]

I realised I also didn't add it to this file, apologies for the mistake.

Automated message: A couple checks before merge. 1) This switches the Linux target to aarch64 on ubuntu-22.04; do we already have aarch64 cross-compile/toolchain (or QEMU) set up? Without it, this will likely fail. 2) This replaces the x86_64 Linux artifact in this workflow; if there isn’t another workflow producing x86_64 builds, we’ll lose them. If the goal is just adding rpm, consider keeping x86_64 and only adding --bundles deb,rpm; otherwise a dedicated aarch64 Linux workflow may be clearer.
