fix(ci): fix CI workflow (#333)

Update the CI workflow configuration in .github/workflows/test.yml
to enhance compatibility, improve dependency management, and
ensure the use of the latest tools. Key changes include upgrading
GitHub Actions versions, adding new dependencies, and explicitly
installing the latest version of LuaRocks.

Also drop a redundant checkout action.
