Fix label action

[dstansby]

This seems to have gone wrong in #2736, so trying to fix here.

Because the job is defined using pull_request_target, it's run from the GH actions config on the main branch, so this will need merging to fix the job.

This proved to require an odd and detailed intervention. Assuming the efforts in #2747 are accepted, I think this PR can be closed

I like the simplicity of this fix, but how do we know if it works? Should we merge and see what happens?

[dstansby]

Yes, it will need merging to verify if it works .

[moradology]

Can technically swap over to target pull_request but I'd say just pull the trigger and clean up later

[jhamman]

Can we get this merged now? The failing labeler is causing CI checks to fail on all PRs.

[dstansby]

Sure, it just needs a maintainer to review/approve/merge.

@d-v-b , will auto-merge happen if the labeler run fails? (as it will, since it won't take action until its in main)

I was wondering the same thing. we shall see!
