Automatically append the OS architecture to the cache key

[mitesch]

We had a user report as part of our Ubuntu arm64 rollout that tracked back to the apt package cache accidentally being shared between the x64 runners and arm64 runners. This resulted in some odd errors.

This change will add the CPU architecture to the key to be hashed.

I am not adding it if it is current "normal" case of x86_64 for ubuntu-latest, ubuntu-24.04, and ubuntu-22.04 in an effort to not needlessly invalidate caches.

Here's an example run using my branch

[awalsh128]

Looks good, I'd like to add this to the CI as well @ https://github.com/awalsh128/cache-apt-pkgs-action-ci/actions

Can you issue a PR for a test, I will approve and then we can run against this. Especially since this is a master PR.

Is this going to be merged at some point? I think my tests are failing due to cache being shared between archs here https://github.com/fenio/pv-mounter/actions/runs/15924537506
