ci: remove `if: github.event.issue.pull_request` from `labeler.yml`

`github.event.issue.pull_request` is an object, not a boolean.
This is the root cause of why the step that is supposed to remove labels
is always skipped. Having this condition in place is not necessary since
the workflow is run on the `pull_request_target` event.
