fix(ci): allow ARM64 Alpine artifact upload to fail gracefully

The upload-artifact JS action cannot run inside Alpine containers
on ARM64 runners. Add continue-on-error for aarch64 builds since
release.yml has dedicated upload-arm-static and upload-android-static
jobs that handle these uploads via gh CLI.
