Poor Information returned on Windows through pre-commit

[jdewinter3Cloud]

Tried adding this to my project, and this is what I see from output:

action validator.........................................................Failed
- hook id: action-validator
- exit code: 1

It would be helpful if there was more information on how to debug this issue, and how to see where there are bad parts of the GitHub files.

The action-validator tool itself reports the nature of the failure that occurred, and the script that pre-commit uses to run action-validator does not appear to suppress that output, so this would seem to be a problem with pre-commit itself.

If there's any way that the .pre-commit-hooks.yaml that we ship could be improved, to tell pre-commit to display output on failure, I'd accept a PR to fix that, but I'm not a pre-commit user myself, and don't have a great desire to learn anything about it, so I won't be able to fix this myself. Perhaps @MatthieuBizien has some ideas, as he wrote the original pre-commit PR.
