Updates 'setup-ruby' to v1 in the Jekyll Workflow Template

[eliduke]

Recently started a new GitHub Pages / Jekyll project, and was surprised to see the setup-ruby action was still tied to a very old and specific version. Not sure why it's still held there, but I was getting some errors during my first couple deploys and I couldn't figure out what was going on!

I upgraded a bunch of my own personal projects to v1 a while back, and I had just assumed that the Jekyll workflow template would have been updated as well.

Thoughts? Concerns?

I had the same issues! The workflow is currently pinned to setup-rubyv1207.0 which produces this error:

Using Bundler 4.0.1 from Gemfile.lock BUNDLED WITH 4.0.1
/opt/hostedtoolcache/Ruby/3.1.6/x64/bin/gem install bundler -v 4.0.1
ERROR:  Error installing bundler:
 bundler-4.0.1 requires Ruby version >= 3.2.0. The current ruby version is 3.1.6.

I tried upgrading incrementally:

• setup-rubyv1.132.0 (added Ruby 3.2.0 support) still fails with Error: Unsupported platform ubuntu-24.04 on latest-ubuntu.
• setup-rubyv1.177.0 (added ubuntu-24.04 support) works!

So the minimum fix seems to be pinning to v1.177.0. We should also explicitly pin the runner to ubuntu-24.04 to prevent breakage in the future if we go this route.

Is there a need to pin it to a specific version beyond just v1? Doesn't that automatically pull the latest minor version as well?
