What changes were proposed in this pull request?

Use custom BeEqualToIsFatal matcher instead of assert in ExecutorSuite.testThrowable

Why are the changes needed?

  1. simplify assert expression and make check more readable
  2. improve error message and print exception stack trace
  3. help with troubleshooting test failure (https://github.com/vrozov/spark/actions/runs/19272277095/job/55103520062)
