hack/verify-all should output the specific tests that failed

[robscott]

What would you like to be added:
When a test fails in hack/verify-all.sh, we should output the failed tests at the end of the run.

Why this is needed:
Debugging test logs is very complicated. For example, consider this recent failure where the output looked like this:

�[0;32mSUCCESS: hack/../hack/verify-yamllint.sh �[0m
make: *** [Makefile:113: verify] Error 1

The actual problematic logs were:

level=warning msg="[config_reader] The configuration option `linters.govet.check-shadowing` is deprecated. Please enable `shadow` instead, if you are not using `enable-all`."
conformance/tests/backendtlspolicy-normative.go:22: File is not `goimports`-ed with -local sigs.k8s.io/gateway-api (goimports)
	"k8s.io/apimachinery/pkg/types"
�[0;31mTest FAILED: hack/../hack/verify-golint.sh �[0m

It would be great to at least show the specific script that failed closer to the final output so it's more clear why make verify failed.

The raw file is difficult to read.

Prow has a feature that it can only list the colored line in a build.log. Something like this - https://prow.k8s.io/view/gs/kubernetes-jenkins/pr-logs/pull/kubernetes-sigs_gateway-api/3212/pull-gateway-api-verify/1825622946182336512.

I can easily locate all errors from there, and only the problem is it has a bug. It starts to list the wrong lines on the server side after I click Analyze button even I don't have any privilege; I don't see there is any way to recover this operation.
