fix(queue): use label= (singular) not labels= (plural) for Gitea 1.22.6 API

Gitea 1.22.6's /repos/{R}/issues endpoint accepts `label` (singular)
for filtering by a single label name, not `labels` (plural). Using the
wrong param silently returns 0 results, so the queue cron has been
picking no PRs for every tick.

Fixes the merge queue silently returning 0 queued PRs.
