Intel Linux bottle cache not working due to ARM Linux

[cho-m]

On CI re-runs with both ARM and Intel Linux, the Intel runner may download the cache for ARM, e.g. linux-self-hosted-1 downloaded bottles_ubuntu-22.04-arm at https://github.com/Homebrew/homebrew-core/actions/runs/14160991497/job/39666467650?pr=206362#step:4:36

A workaround could be to modify the pattern match to check for the arm suffix though checking for negation is not that clean.

It did work in https://github.com/Homebrew/homebrew-core/actions/runs/14421742385/job/40445241798?pr=217231#step:4:36 though could improve to avoid downloading arm bottles on x86_64

We probably should clean up the artifact names so that it's something like bottles_linux-x86_64 and bottles_linux-arm64 so that we don't have to try to match specifically against ubuntu-22.04-arm to include/exclude bottle artifacts.

I don't see how this breaks the bottle cache, though -- at worst it should just be introducing unnecessary downloads, instead of preventing bottles from being cached.
