workflow: Downgrade github runner

Due to an
[issue](actions/runner-images#11471)
with Ubuntu 24.04 20250120.5.0 runner image
we have been seeing failures in our multi-arch images for
the last few days which is blocking the release. I assume that
the issue is something related to qemu, so downgrade to 22.04
until this issue is resolved.
