Caps the activeadmin dependency at < 4.0.0.a so bundler can no longer resolve an ActiveAdmin 4 prerelease. This is the gemspec 1.3.0 will ship for ActiveAdmin 3 from current master.

RubyGems sorts 4.0.0.beta23 below 4.0, so the old < 4.0 admitted every ActiveAdmin 4 beta, and this jQuery plugin does not work there. .a is the lowest possible 4.0.0 prerelease, so the cap excludes all of them.

The suite was red on a fresh bundle: Ransack 6 raises when a model leaves ransackable_associations undefined. The dummy app template now defines it as [] for Author.

Release impact: none on its own. This becomes part of 1.3.0, a minor release. ActiveAdmin 4 support will ship separately as 2.0.0.

Verified: bundle exec rspec spec/filters_visibility_spec.rb passes (5 examples) on Ruby 3.4, Rails 8.1.4.1, ActiveAdmin 3.5.2, Ransack 6.1.0.
