Subject: [PATCH] Pin json below 3.0 for the test suite

json 3.0.0 removed the quirks_mode option, but ActiveSupport 7.2.3.x
still passes it to JSON.generate. Once ActiveSupport's JSON extensions
are loaded, Hash#to_json raises "ArgumentError: unknown keyword:
quirks_mode".

In the test suite ActiveSupport is only loaded when
spec/persistence/cookie_adapter_spec.rb requires "rails", so specs that
serialize JSON fail only when that file runs earlier in the random
order.

ActiveSupport 7.2.4 no longer passes quirks_mode, but it caps
connection_pool below 3. On Ruby >= 3.2, Bundler resolves
connection_pool 3.x with ActiveSupport 7.2.3.2 instead, so the affected
jobs are Ruby >= 3.2 with Rails 7.x. Ruby 3.1 resolves ActiveSupport
7.2.4, and Rails 8.x does not pass quirks_mode either.

This only affects the development Gemfile, not the gemspec.
