Testing against Rails 8.1

- Updated Appraisals to include a new entry for Rails 8.1 with the appropriate railties version.
- Modified GitHub Actions workflow to include the new Rails 8.1 gemfile in the CI process.
- Created a new gemfile for Rails 8.1 to manage dependencies.

This ensures compatibility with the latest Rails version and enhances CI testing.
