Describe the bug

I am creating a pipeline which automatically updates FluxCD via a pull request. I was running into some permissions issues, in which I found that flux check always returns with an exit code of 0 even if not all deployments were ready:

Note the first arrow points to the result of flux check --pre which is as expected since it says all checks passed. The second arrow points to the result of flux check which should return a non-zero status code since the checks failed.

Steps to reproduce

1. Install Flux.
2. Create a ServiceAccount missing some permissions required for flux check to run (reference What RBAC permissions are required for `flux check` to run successfully? #5217 (comment)).
3. Run flux check.
4. Run echo $? to see the status code.

Expected behavior

echo $? should return a non-zero status code if the result is "check failed".
