fix(release): use if/else for protoc install, add apt-get update for aarch64

The || chain causes both dnf and yum to run on x86_64 manylinux
(AlmaLinux 8 has yum as alias for dnf) — both complete, then
apt-get is tried and fails with 'command not found'.

The aarch64 rust-cross container is Debian-based and requires
apt-get update before install (stale package list = 404 errors).

Use if/else: dnf for manylinux x86_64, apt-get for aarch64 cross.

Closes #55
