Fix triage labeling workflow

[hslatman]

The checkout was removed in 6ec0ba4. The checkout action is in fact used.

It seems to just be using gh, why does it need a checkout?

I'm debugging action runs in a few repos. Take this for example: https://github.com/smallstep/cli/actions/workflows/triage.yml. It started failing recently, mentioning no git repository was present when labeling the PR. The removal of the checkout seemed like a likely cause, but testing it out, doesn't seem to resolve it yet.

I've dug and it is the underlying issue, yes. But it's clearly a bug in gh.

Could we try this first instead please, to avoid cloning (in case we can avoid it)?

gh api \
      --method POST \
      repos/${{ github.repository }}/issues/${{ github.event.pull_request.number }}/labels \
      --field 'labels[]=needs triage'

maybe contents: read is not needed?
