The Lint workflow on the 6.0-stable branch is currently failing:
https://github.com/redmine/redmine/actions/runs/12647045791/job/35238740462

Run ruby/setup-ruby@55283cc23133118229fd3f97f9336ee23a179fcf
Error: The current runner (ubuntu-24.04-x64) was detected as self-hosted because the platform does not match a GitHub-hosted runner image (or that image is deprecated and no longer supported).
...

The issue is caused by using a version of ruby/setup-ruby that does not support Ubuntu 24.04.

This patch fixes the issue by updating the workflow to always use the latest version of ruby/setup-ruby v1:
