ci(github): support arm in the official release

[sideninja]

Add build variant for linux/arm platform.

The PR modifies the goreleaser config to support building for arm architecture. It also modifies the release-official action for halovisor to support building for the arm.

issue: #1984

Tested goreleaser build locally:

goreleaser release --snapshot --skip publish --clean

Follow up: should we modify the goreleaser to also include the halovisor and make it more consistent? why is halovisor part of the release action and not included in goreleaser config?

todo: need to validate the whole action against a fork.
