8523d8c ci: display logs of failed tests automatically (furszy)

Pull request description:

  Saw it here https://github.com/bitcoin/bitcoin/actions/runs/11488618084/job/31975712362?pr=31000.

  The 'test-each-commit' and 'win64' CI jobs currently do not display test logs when an error occurs, making it almost impossible to debug issues that don't arise locally. Fix this by setting the CTest `--output-on-failure` flag (per [README](https://github.com/bitcoin/bitcoin/blob/2f40e453ccdf5f75b599fc7168abd512510686c5/src/test/README.md?plain=1#L130)).
