Doesn't support ActiveRecord >=7.2?

[EdgeToLife]

The gem does not install via Rubygems due to a compatibility error.

Steps to reproduce the error:

1. Create new app: rails new test_app
2. Add gem 'active_record_upsert' to Gemfile
3. bundle

    Because rails >= 7.2.2.1, < 8.0.0.beta1 depends on activerecord = 7.2.2.1
      and rails >= 7.2.2, < 7.2.2.1 depends on activerecord = 7.2.2,
      rails >= 7.2.2, < 8.0.0.beta1 requires activerecord = 7.2.2 OR = 7.2.2.1.
    And because rails >= 7.2.1.2, < 7.2.2 depends on activerecord = 7.2.1.2,
      rails >= 7.2.1.2, < 8.0.0.beta1 requires activerecord = 7.2.1.2 OR = 7.2.2 OR = 7.2.2.1.
(1) So, because rails >= 7.2.1.1, < 7.2.1.2 depends on activerecord = 7.2.1.1
      and rails >= 7.2.1, < 7.2.1.1 depends on activerecord = 7.2.1,
      rails >= 7.2.1, < 8.0.0.beta1 requires activerecord = 7.2.1 OR = 7.2.1.1 OR = 7.2.1.2 OR = 7.2.2 OR = 7.2.2.1.

    Because active_record_upsert >= 0.6.1, < 0.6.3 depends on activerecord ~> 5.0.0.beta4
      and active_record_upsert < 0.6.1 depends on activerecord ~> 5.0.0.beta2,
      active_record_upsert < 0.6.3 requires activerecord >= 5.0.0.beta2, < 5.1.A.
    And because active_record_upsert >= 0.6.3, < 0.7.0 depends on activerecord >= 5.0, < 5.1,
      active_record_upsert < 0.7.0 requires activerecord >= 5.0.0.beta2, < 5.1.
    And because active_record_upsert >= 0.7.0, < 0.7.3 depends on activerecord >= 5.0, < 5.2
      and active_record_upsert >= 0.7.3, < 0.9.5 depends on activerecord >= 5.0, < 6.0,
      active_record_upsert < 0.9.5 requires activerecord >= 5.0.0.beta2, < 6.0.
    And because active_record_upsert >= 0.9.5, < 0.10.0 depends on activerecord >= 5.0, < 6.1
      and active_record_upsert >= 0.10.0, < 0.11.0 depends on activerecord >= 5.0, < 6.2,
      active_record_upsert < 0.11.0 requires activerecord >= 5.0.0.beta2, < 6.2.
    And because active_record_upsert >= 0.11.0, < 0.11.2 depends on activerecord >= 5.2, < 7.1
      and active_record_upsert >= 0.11.2 depends on activerecord >= 5.2, < 7.2,
      activerecord >= 5.0.0.beta2, < 7.2 is required.
    And because rails >= 7.2.1, < 8.0.0.beta1 requires activerecord = 7.2.1 OR = 7.2.1.1 OR = 7.2.1.2 OR = 7.2.2 OR = 7.2.2.1 (1),
      rails >= 7.2.1, < 8.0.0.beta1 cannot be used.
    So, because Gemfile depends on rails ~> 7.2.1,
      version solving has failed.

Even if I explicitly specify the latest version in Gemfile, I still get a compatibility error.

gem 'active_record_upsert', '0.11.2' or gem 'active_record_upsert', '~> 0.11.2'

Because rails >= 7.2.2, < 7.2.2.1 depends on activerecord = 7.2.2
  and rails >= 7.2.1.2, < 7.2.2 depends on activerecord = 7.2.1.2,
  rails >= 7.2.1.2, < 7.2.2.1 requires activerecord = 7.2.1.2 OR = 7.2.2.
And because rails >= 7.2.1.1, < 7.2.1.2 depends on activerecord = 7.2.1.1
  and rails >= 7.2.1, < 7.2.1.1 depends on activerecord = 7.2.1,
  rails >= 7.2.1, < 7.2.2.1 requires activerecord = 7.2.1 OR = 7.2.1.1 OR = 7.2.1.2 OR = 7.2.2.
And because rails >= 7.2.2.1, < 8.0.0.beta1 depends on activerecord = 7.2.2.1
  and active_record_upsert >= 0.11.2 depends on activerecord >= 5.2, < 7.2,
  active_record_upsert >= 0.11.2 is incompatible with rails >= 7.2.1, < 8.0.0.beta1.
So, because Gemfile depends on rails ~> 7.2.1
  and Gemfile depends on active_record_upsert = 0.11.2,
  version solving has failed.

Maybe I'm doing something wrong?
