que test suite failures

[arielvalentin]

The nightly build for queue started failing with what seems to be incompatibilities with newer versions of Rails.

This is temporarily fixed by #1112, by preventing the tests from running on 7.2.

que-rb/que#423 at commit dcdbe94 will get the tests to pass with Rails 7.2. However, it's still in review. Further discussion in que-rb/que#425.
