Subject: [PATCH 2/2] fix: update liquid gem to 4.0.4 to fix Ruby 3.3
 compatibility

liquid 4.0.3 calls String#tainted? which was removed in Ruby 3.2+,
causing the Jekyll build to fail with NoMethodError.
Upgrading to 4.0.4 removes that call.

Also add .devenv/scripts/ci/run-act.sh to test the workflow locally
with act.
