Drop 32bit arm from package builds

[saschagrunert]

What type of PR is this?

/kind cleanup

What this PR does / why we need it:

We stopped building 32bit arm releases in kubernetes/kubernetes#115742, means we cannot publish packages for that platform any more.

Which issue(s) this PR fixes:

Refers to: kubernetes/sig-release#2189

And:

• [Failing Test] build-master kubernetes#116492
• Do we need to support linux/arm build/release artifacts in kubernetes (32-bit arm for Raspberry PIs) kubernetes#115738
• [Failing Test] build-master kubernetes#115675

Special notes for your reviewer:

We do not distinguish package builds for release branches and minor releases right now. Means this change will affect both of them.

Does this PR introduce a user-facing change?

Stopped building packages for 32 bit ARM platforms for Kubernetes >= v1.27.0.

I guess having to drop existing releases from (arm) packaging, is a side-effect of

• packaging specs should be per-kubernetes version and in-tree (k/k) #1913

that requirement seems new, right? otherwise, how did we introduce darwin/arm64 builds in 1.21 in kubernetes/kubernetes#97743 without breaking releases on still-supported <1.20 versions?

[liggitt]

the architectures we release for seem like they should be able to be overridden per minor version

I modified the PR to drop the arm architecture only for Kubernetes >= v1.27.

@saschagrunert Should we keep this on hold until patch releases are not out?
