[Actions] TruffleRuby checks fails silently

[meuble]

Description

TruffleRuby fails to run the tests without errors, but this doesn't prevent the CI to raise any warning.

To Reproduce

Run the tests on TruffleRuby.

Expected behavior

I would expect that if some of the tests doesn't succeed, the CI should prevent the PR to be accepted and should display warnings.

I would also expect the tests to fully succeed and TruffelRuby.

Additional context

See the following PR for example (one accepted, on pending — currently at least):

• https://github.com/faker-ruby/faker/pull/2289/checks?check_run_id=2201015174
• https://github.com/faker-ruby/faker/pull/2308/checks?check_run_id=2443282120
