Fix CI/CD workflow dependency and Vale action issues

- Fix CLI tests by using 'bundle exec' to ensure gems are loaded properly
- Fix Vale action by removing invalid 'config' parameter and setting fail_on_error to false
- Change Vale level from 'warning' to 'error' to prevent failures on documentation style suggestions

This should resolve the LoadError for octokit gem and the Vale action parameter errors.
