chore: test Rails 7.1 on JRuby 9.4.6.0

[joshuap]

This is currently failing. When I run bundle update, it fails when installing psych (which is required by rdoc):

Fetching psych 5.1.2 (was 4.0.3)

To see why this extension failed to compile, please check the mkmf.log which can
be found here:

Gem files will remain installed in

for inspection.

An error occurred while installing psych (5.1.2), and Bundler cannot
continue.
Make sure that `gem install psych -v '5.1.2' --source 'https://rubygems.org/'`
succeeds before bundling.

In Gemfile:
  rdoc was resolved to 6.6.3.1, which depends on
    psych

...which is odd, because running the suggested command to install psych by itself succeeds:

λ  honeybadger-ruby jruby-rails7.1 ✓ gem install psych -v '5.1.2' --source 'https://rubygems.org/'
  jar dependencies for psych-5.1.2-java.gemspec . . .
      org.snakeyaml:snakeyaml-engine:2.7:compile
Successfully installed psych-5.1.2-java
1 gem installed

After we get bundle install to work, we then need to install the Rails 7.1 gemfile with bundle exec appraisal rails7.1 bundle exec install.

cc @headius in case this is a quick/known issue.

This seems like it's trying to install the native extension psych rather than the JRuby version that has no native code. I'm not sure why this would happen unless a version of psych was released without the JRuby version.

FWIW there are some in-progress issues with JRuby and Rails 7.1 but I'm actively working on resolving them this week.
