fix(ci): install jq before sop-tier-check script runs

Root cause: Gitea Actions runners (ubuntu-latest) do not bundle jq.
The sop-tier-check.sh script requires jq for all JSON API parsing;
without it, the script exits at line 67 with "jq: command not found",
producing "Failing after N seconds" on every PR.

Fix: add apt-get install -y jq step before the script run.
