Message "TestRunFinished" always report "success: false" whatever the result of the execution is

[aurelien-reeves]

Describe the bug
The "TestRunFinished" message does not report "success: true" if the run was actually ok.
It is actually not implemented at all. See the message_builder formatter: it does not set the success for the TestRunFinished message: https://github.com/cucumber/cucumber-ruby/blob/main/lib/cucumber/formatter/message_builder.rb#L229

To Reproduce
Run cucumber --format message. Whatever your tests are failing or passing, {"testRunFinished":{"success":false is always reported.

Expected behavior
{"testRunFinished":{"success": depends on the execution and may be true if no failure is reported. It should match the result of the cucumber command.
