Test-infra: Label plugin parsing problem ("The label(s) kind/ cannot be applied")

[benmoss]

What happened:
Comments to add labels to issues seem to occasionally parse incorrectly, making the Prow bot comment

The label(s) kind/ cannot be applied, because the repository doesn't have them

It still does apply the expected labels.

What you expected to happen:
No complaint about a kind/ label.

How to reproduce it (as minimally and precisely as possible):
Not sure. I checked the test cases and they seem to cover this, I think I need to see the raw GitHub comment body to be sure.

This was fixed in https://github.com/kubernetes/test-infra/pull/19391 yesterday. The changes should get pulled in once https://github.com/kubernetes/test-infra/pull/19396 merged. :)
