Release new version compatible with Rails 8.0

Hi @abicky !

Would you mind if I ask for a new version to be published, including #10 ? I'm planning to update my team's Rails app to 8.0.

I've just released v0.1.4.
I thought I didn't need to release a new version because I hadn't modified the main code but I realized that the previous version had the condition spec.add_runtime_dependency "activerecord", ">= 6", "< 8" (a0e840f)...

@abicky, I really appreciate your quick action!
