I opened the PR to investigate https://bugs.ruby-lang.org/issues/21329, which has now been fixed. Do we still need the change here?
Sorry for the delay in responding 🙏

It seems ok to replace ruby/setup-ruby with ruby/setup-ruby-pkgs simply.

    - name: Set up Ruby
      uses: ruby/setup-ruby-pkgs@v1
      with:
        ruby-version: ${{ matrix.ruby }}
        bundler-cache: true # 'bundle install' and cache
        msys2: gperf
        choco: gperf

And needed to add git config to suppress warnings by msys2 gperf.
