Bump ci-setup-workflow to v2.3.1 by ludfjig · Pull Request #1984 · hyperlight-dev/hyperlight

ludfjig · 2026-10-26T19:57:31Z

Bumps ci-setup-workflow to v2.3.1 in every workflow. ubuntu-latest is Ubuntu 26.04, where apt.llvm.org has no LLVM 18 and v2.3.0 fails. This breaks check-golden-label and post-benchmark-comment. v2.3.1 (hyperlight-dev/ci-setup-workflow#25) installs LLVM 18 from the Ubuntu archive.
