revert: restore workflows to EXACT working version from August

CRITICAL: Restored the EXACT workflow configuration that worked:
- Ubuntu 20.04 containers (as it was)
- libicu66 (as it was)
- tar format NOT tar.gz (as it was)
- Git installed in container setup (as it was)
- ARM64 cross-compilation preserved

This is the EXACT configuration from commit 7b8e2e8 that WORKED.
